Re: OT: Configuring 2600 for Cable Modem Router

Because of my service provider limitations, I have set my "external"
interface to be a DHCP Client. I then have an internal DHCP Pool for the
other interface, specifying their DNS, the DHCP Pool and the DFG etc.

This is all working fine and I am getting an IP Address from the Service
Provider. I also have setup a default route pointing to the "external"
interface.

However, I am not able to browse the internet yet, because I believe I need
to setup a NAT.

Can anyone suggest how I might setup this NAT? Here is my config now...

ip subnet-zero
no ip source-route
ip cef
no ip domain-lookup
!
ip dhcp pool localdhcp
   network 192.168.1.0 255.255.255.0
   netbios-node-type h-node
   default-router 192.168.1.254
   dns-server 204.127.203.135 216.148.225.135
   lease 2
!
ip audit notify log
ip audit po max-events 100
