Hi, all. Got a Routerboard 750G to replace a slowly dying Cisco (Linksys) router because I heard good things about these lovely routers, plus customisability is amazing (maybe too amazing).

This may be a stupid question but bare with me, it's my first time working with Routerboard stuff.

I set everything nicely, Internet is running, LAN is running but it only works on Ether2, which is fine as I got the main switch connected to that. Problem is the other 3 Ether ports, they don't seem to be active. I initially assume that since these 3 ports are slaves they'll take the master's (which is the perfectly working Ether2. Looking at http://wiki.mikrotik.com/wiki/Manual:In ... face_state

That's all I have to do.. or not?

I have another question, which is about Port forwarding. I assume this is done via Firewall rules. We have one of the PC running a server for testing, which is 192.168.10.67, I set up AWS to route it here and in the old router I simply port forwarded 80 and 443 to 192.168.10.67 and it works. Unfortunately, doing something similar in firewall rules didn't work for me.

I tried this:

Replacing the numbers there with what we have but doesn't seem to be an answer.

OK, I figured out the port forwarding issue. There's one thing I forgot to do, that is mascaraing locally. So for those who have problems, to forward outside traffic on a specific port to a local address you need to do this:

WAN IP = 9x.xxx.x8.xx4
LAN IP you want to forward to = 192.168.10.67
Port I want to forward = 80

You pretty much need these rules added:
Of course you also need the WAN mascaraing as well but I had that rule by default. It's essentially same as the above but:
Still not sure why I only have Internet connection on Ether2 only, maybe it's simply DHCP is not serving any other ports? I'll try to figure it out myself but any help will speed up my progress.

Answer to my initial question was a silly one. I assumed it didn't work, when in fact it did. The problem was that the NAS that is connected to ether3 would get an IP from the DHCP even though I explicitly set to a static one in ARP table. Which confused me as it didn't occur to check if it was assigned a different IP and seeing 1 MAC with 2 different IPs is just weird. Funny enough all the other other devices that I set to be static behave nicely. It also seems to always go for the same IP address. In the end I had to set the IP statically within the actual NAS.

I just had finished writing my post but it seems you have figured everything out by yourself

Congratulations

Thanks. I never set up a Mikrotik router before so I reckoned, it would be faster to solve the problem if I asked here as well as trying to figure out it myself.

One more question. How do I go about setting the static IPs for the clients? Setting them statically just in ARP table didn't do the trick it seems. Do I need to tinker with the DHCP as well? I see I can set static leases there. Err, not sure if that's the proper way of doing it.

Yes you make clients use the same IPs by setting them to be static in the DHCP server section.
