internet router

I have 1 public Ip on my internet router, I have about 4 different subnets connecting through it, Do I need to set port address translation on this router, How do I do it ? Can someone show me a quick config ?

thanks

Re: internet router

hi

ofcourse you will have to configure PAT in your scenario.

in normal conditions the configs looks like this ..

interface fastethernet 0/0

ip address x.x.x.1 255.255.255.0

ip nat inside

interface serial 0

ip address y.y.y.2 255.255.255.252

ip nat outside

ip nat inside source list 1 interface Serial0 overload

access-list 1 permit x.x.x.0 0.0.0.255

x.x.x.0/24 -- local lan address space.

y.y.y.0/30 -- wan connectivity address space.

confirm how you have put 4 subnets and how is it configured ? is it on the same router ?
