Using an external IP without NAT
Posted: Sat Nov 12, 2011 3:35 am
My ISP gives me 3 usable IP addresses, one is the IP of the router, and the other two are in a separate block, a /29 so two usable.
Currently I have the router set up to just use the one IP and to do NAT. Behind this I have my Windows machines.
However I also have a Linux machine that I would like to connect directly to the internet. I would like to give it one of my external IPs and plug it directly into the Billion on port #4, then have the Billion route packets to it without any form of NAT being involved.
I can't figure out how to set this up. I tried creating a port-based VLAN for port #4. If I ssh into the router this vlan shows up as an interface called br1. However if I then go back to the static routes section of the web interface, I can't set up a rule to forward to br1 as the only interfaces in the dropdown are my adsl interface and the main br0 interface.
Any ideas how I'd do this?
