What is recommended for a home network with N wifi? The RB751 seems the obvious choice, but it is not a gigabit device. If I want to have gigabit should I use an RB450G? And then some sort of wifi AP? The Ubiquiti PowerAPN was mentioned on the first page of this thread. I have a consumer Buffalo router with G wifi that has an antenna that is hanging by its wire and a bad habit of freezing every time I surf a little too hard. I am in a NETWORKING TECHNOLOGIES program (CCNA mill) and would like something to mess about with.

COCKMOUTH.GIF posted:I'm more or less in the same boat and have been for some time. The RB751 sounds perfect for me, but ideally I'd like internal gigabit switching. I suppose one could just connect a gigabit switch to one of the ports on the Mikrotik but that's kind of a half-rear end solution. Are there plans for something like an RB751G? I can't remember. Maybe I am being dumb, but isn't the other problem with that setup that N wifi is faster than fast ethernet? You are effectively limiting fancy N wifi to 100Mbit/s, rite?

CrazyLittle posted:Also, wireless spectrum is divided among the number of active clients connected, so 3 people connected to 150mbps wifi-n get ~50mb each, whereas 3 people connected to a 1gb switch can have 1gb each to other switch ports. Yeah, I suppose for most purposes gigabit is not usually a factor. I have a wired file server that copies files to a single wireless device on the LAN and I think gigabit might actually be effective, but I guess it is a very limited use case. Also, what technically is an active client? If some clients are idle, does a single active client get closer to full bandwidth, or is bandwidth divided between connected devices no matter what? Also also I have an RB450G in the mail I am excited. I wonder how many days it will take me to figure it out :o.

Woah, this post brought to you by an RB450G! I have so many questions. . . I am using this for a home LAN, btw. This device has 5 ports. One port is designated for the WAN input, and the other 4 are just to be used as a switch for the LAN. The device worked right out of the box with the default config, but also I tried to scrap that and use the anypony guide (http://users.moscow.com/groovydave/mt/) to get it going from scratch on my own. That sort of got me there, but the dhcp server never seemed very happy. 1. The default config differs from the anypony guide in that it does not have you set a master port and slave ports for the switch. Reading the mikrotik wiki on the switch chip (http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features) it seems like doing the master/slave format is more efficient, as traffic on the LAN never has to be processed by the router cpu. Is this correct? I am not sure what the default config is doing. I think it bridges all the ports? If I do use the switch chip with master/slave, I don't want to switch-all-ports, right? As eth1 is going to be the WAN input and doesn't need to be switched? 2. Also, the default config creates some firewall filters that anypony doesn't touch on: code:
3. Also, I set the services to only be reachable from the LAN. I think: code:
I think that is all for now! I am sure to have many questions about QoS coming up.

Weird Uncle Dave posted:This is true, but if you're doing anything else at all to the traffic (like, say, QoS'ing it, as you've mentioned) it won't work. You might as well just get rid of the switching stuff and go straight to creating a bridge interface and sticking ether2-ether5 in there now. Hey! Thank you for your help. Sorry about my delay in replying, holidays and all that. . . I am not sure I understand why switching doesn't allow QoS, etc. See this image: http://wiki.mikrotik.com/wiki/File:Switch4.png So I couldn't do QoS on traffic that never leaves the LAN, but if a LAN host wants to talk to the WAN, I can QoS that, right? Since this is just for a home network, I can't say that there is a whole lot of steady traffic bumping around the LAN side by itself. Am I completely misunderstanding this? Two new questions! I have what claim to be CAT6 cables connecting my PC to the 450G, but it rarely shows a gigabit connection. When first plugged in the PC reports gigabit, but it seems to drop to 100Mbit after dhcp, or something. I have no idea how to trouble shoot this. Looking at the awesome diagram from feld, I "get" the forward/input/output chains now, I think. Trying to do QoS on ssh traffic: code:

CuddleChunks posted:Is your mark rule triggering? Check the firewall tab in Winbox (my preferred way to puzzle these out). Look at the packet count and when you try to make an SSH connection does the rule up its count by one? Ah, I am actually getting somewhere with this now, thank you! You are correct that the mangle rule needed to use the forward chain, not the output chain. Then action is seen on the rule when I ssh. Nothing was seen on the queue tree, however, until I again changed the mangle rule, switching mark-connection to mark-packet. Now the queue tree lights up as well! So now it appears to be working, but I am not 100% sure things are all that faster. What I have created is only affecting the outgoing packets, correct? They are not affecting incoming packets? Also also, this further highlights my misunderstanding of input/output/forward chains. When I looked at feld's chart, I was imagining that traffic that never leaves the LAN doesn't even come into play there, and then any traffic from the LAN that has to travel over to the WAN side enters where it says "Socket and Output routing". Now I see that that is really saying locally generated traffic, ie traffic generated by the router itself, and that all traffic enters the router on the top left, both WAN and LAN. Am I getting closer now? Also, for the QoS, I really did pull those limit numbers out of my rear end. I have no idea what they really need to be :/

I am trying to setup a rule to catch and prioritize my own bit torrent traffic on my home network. It is encrypted traffic, so the regular L7 rules don't seem to see it. My torrent program has an option to set a "Peer TOS Byte" in each IP header. I also have the same option in Crashplan (a cloud backup service). How do I mark these packets with a mangle rule? I don't see anything under the mangle options that seems to correspond to this field.

CuddleChunks posted:Lock your torrent client to a specific port on your computer. Build your rule to queue traffic that talks to that port and now you can shape it like a mofo. Yeah, that is what I ended up doing. I am having a weird problem with my Roku (netflix streaming device). It connects to the wifi access point which is connected to the RB450G. It works perfectly, but it does not show up in the DHCP leases of the RB450G, which is running the only DHCP server on the network. Why would this be? It is very confusing! I am trying to have QoS rules so that the Roku devices gets high priority, as well as any Netflix traffic, but it is turning out to be difficult for me, and I think the fact that the RB450G seems unaware of the Roku might be part of the problem. add action=mark-packet chain=prerouting comment=Roku disabled=no new-packet-mark=priority_roku passthrough=no src-mac-address=00:0D:4B:11:11:11 This catches some traffic, 46 MB in a few days, but it has streamed many movies since then, so it is only catching a small fraction of it. I would be happy to match it to IP and assign the roku a static lease, but that is kinda hard to do since the RB450G doesn't seem to think the current lease exists in the first place! Then there is the issue of Netflix streaming in a browser from most any computer in the house. I haven't found a layer 7 protocol for netflix. Googling has only found people with huge lists of IP addresses of netflix servers that they build rules off of. Maybe this is the only way?

CuddleChunks posted:Are you sure it's set for DHCP? Also, you're not seeing it in winbox under IP -> DHCP-Server -> Leases? It does appear in the ARP table, but still not in the list of DHCP leases. It didn't even occur to me that the Roku might be set to use a static IP address. I certainly don't remember telling it to do that. . . So I checked the Roku settings, which are very limited, and there is certainly no option for static IP addresses. I redid its little "guided network setup" and now it has a new address and appears in the list of leases and arp table! Whatever! Fixed! What is not fixed, however, is my mangle rule! It still isn't seeing the vast majority of the traffic the roku is creating. other people fucked around with this message at 04:38 on Jan 3, 2012 |

CuddleChunks posted:It looks like it's a static lease. Notice there's no "D" in the dynamic column. If you check the Roku's page does it show that it has that IP address? Did you set the Roku to that static IP so it isn't trying to request DHCP? I made the DHCP lease static, because I was trying to mangle by IP since the mangle-by-mac was never picking it up. The Roku is using .80 via DHCP. I don't think the Roku even has the option to use static ips. I will unstatic it and see what happens. . . edit: Well now it is working. It grabbed .9 with no problem. I swear it wouldn't do this before! Another question, should this queue tree not see all incoming traffic? add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 max-limit=18M name=Incoming parent=global-in priority=8 \ queue=default other people fucked around with this message at 00:46 on Feb 18, 2012 |

CuddleChunks posted:What are you trying to do with your queue? This is the main reference on it: http://wiki.mikrotik.com/wiki/Manual:Queue But if you tell us what you want to accomplish that will help with writing up something that will work. Yeah, I think I understand that the queue only operates on properly marked packets. Here is what I have: code:
All in all, it works quite well as is, but we still have trouble with the Netflix/Roku being very slow to load and dropping the stream if Crashplan/Bit torrent are going nuts. I think part of the problem is that the roku/netflix mangle rule doesn't seem to catch the streaming video. Also the video stream is obviously a download stream. Is it because the streaming stuff is being caught by the TCP ack mangle rule, or is all that streaming stuff UDP? I don't really know what I am talking about.

And I can't get this to work. . . I have a 450G acting as router, and for fun (ha) I am trying to setup the 751G as the wifi access point but on its own network. The 450G is 10.20.30.0/24 and I made the 751G 10.20.40.0/24. I just modified the default config on the 751 so I think I may have missed something.

falz posted:'/export compact' is a lot easier to read Oh. Easier still, if you are not being a moron. I hadn't set up a /30 (or any) network for the link between the two routers. I am a bit rusty. I also had to take the linked ports out of the switch bridge, etc. For comedies sake, I setup RIP! (BGP seemed a little extreme.) http://sprunge.us/GeCH Is /export compact a new command? The 751G has 5.11 and it doesn't recognize it.

This is frustrating. I have 10.20.30.0/24 and 10.20.40.0/24, connected by 192.168.0.0/30. From the 10.20.30.0 router I can ping any host on the other two networks, and the same is true from the 10.20.40.0 router. All hosts can reach the default gateway (i.e. surf the internets). I cannot, however, ping from a host on the 10.20.30.0 network to the 10.20.40.0 or vice versa. Can some one enlighten me as to what is going on here? code:

Muga posted:That's right. I am not strong with mikrotik specially but it sounds like both wireless APs are part of the same broadcast domain and that multicast between them works ( I assume chromecast is using multicast to locate devices). That's all good. Is there some leftover firewall policy on the hAP device getting in the way? Have you tried casting from a google app/stream and not the plex? Maybe there is some plex-specific issue. Otherwise I would just packet capture to see what is actually going on and/or find the chrome casting specifications so you can understand exactly what is supposed to happen and then just step through it.
