Currently we have a 56K frame relay connecting us to our customer location. They have a Cisco 1600 and their internal network is 205.215.201.32 /28 running EIGRP. We are going to be changing that network to 192.168.100.0 /24 and the problem is that network is already being used on our end by another customer so I will have to NAT all traffic back to here. I have the NAT part set up as I will be NATing all traffic to a 192.168.7.0 nat pool. Question is this.. Currently the EIGRP statement is as follows (on both ends)..

Router EIGRP 101
network 205.215.201.0

will this now change to..

Router EIGRP 101
network 192.168.7.0

I think this should be correct, because I don't want EIGRP broadcasting a 192.168.100.0 address. Just for reference I have posted the NAT and EIGRP config. You'll notice there are some devices on their end that I've set up with static routes.

router eigrp 101
network 10.0.0.0 (serial connection)
network 192.168.7.0
no auto-summary
!
ip nat pool NATPOOL 192.168.7.50 192.168.7.100 netmask 255.255.255.0
ip nat inside source list 2 pool NATPOOL
ip nat inside source static 192.168.100.245 192.168.7.245
ip nat inside source static 192.168.100.246 192.168.7.246
ip nat inside source static 192.168.100.247 192.168.7.247
ip nat inside source static 192.168.100.248 192.168.7.248
ip nat inside source static 192.168.100.249 192.168.7.249

access-list 2 permit 192.168.100.0 0.0.0.255

If somoebody can just confirm with me that this is set up correctly, that would be greatly appreciated.

Thanks and have a great weekend.
