I'm getting a Fit-pc2i one of these days, and plan to use it as a router (it's the one with 2 NICs)
However having never setup a linux server as a router before, I'm pretty much in the wilds here. So does anyone have any good links showing how to do this ? I imagine it's pretty simple setting up some static routes and such, but how about firewall and general security concerns of a device hooked directly up onto the Internet ? (that is, my fiber modem)
Finally is it possible to setup the ssh server, so it only answers on the LAN side ?
- How do I setup the actual routing part ?
- What about firewall setup ? (I'm no good with iptables)
- Any other security concerns ? (e.g. services which should be disabled, and so forth)
- Can I setup ssh server so it only answers on the LAN side, thus not opening for SSH on the WAN ? (Maybe just block port 22 in the firewall WAN side ?)
That's a lot of questions - if I should redo them as seperate question in here, let me know - thanks :-)
EDIT: This seems to answers the first question: http://serverfault.com/questions/133405/linux-router-setup
EDIT 2: Might need to mention I plan on using it as a backup server, as well as a LAMP also. In case this changes the needs security-wise.
Also the routing part is for a very small network, and should support WLAN as well (the fit-pc2i has 2 LAN NICs and 1 WLAN NIC) (we only have 3 machines in the office)
