Rookie question: Nat all internal networks to one IP address when accessing the WAN subnet
Currently studying CCNA. I'm attempting to NAT any machine on an internal interface to an IP address on the wan interface
Fast 0/1: 172.25.0.1/24
Fast 0/0: 172.26.0.1/24
Eth 1/0.18: 172.26.18.1/24
Eth 1/0.19: 172.26.19.1/24
There are machines which connect via fast 0/0, and both Eth 1/0 sub interfaces.
Fast 0/1 connects to the internet via 172.25.0.254/24. I'd like to NAT everything from the internal interfaces(2,3,4) to 172.25.0.2 when they attempt to access the internet. I do not want them to NAT when they access other machines on the networks(which are locally connected to this router(2621XM))
The issue at the moment is that the internet router doesn't have a route back for the networks it doesn't have entries for. While writing routes back does fix the problem, I'd like to try it this way too(as a learning exercise)
