Two IPs for one ethernet port?

[blubomber]

I have a cisco 2811 running IOS 12.3(8)T5. I am going to put it between my firewall and my DSL connection (i am also going to be running 2 T1s through it). My current firewall allows me to asign 2 public IPs to the incoming DSL ethernet port. Will the 2811 allow me to do this or do i need another router?

thank you.

I think all Cisco routers support secondary addressing. Try:

ip address x.x.x.x x.x.x.x secondary
