I am having an issue with my NAT configuration. I am fairly knowledable on Cisco routers, but by no means an expert.
Cisco 2611 with two Ethernet ports.
E0/0 (WAN) - DHCP address (69.x.x.228) connected to a Time Warner Cable Modem
E0/1 (LAN) - 10.0.0.1 / 24
E0/0 is configured for NAT outside
E0/1 is configured for NAT inside
ip nat inside source list 115 interface E0/0 overload
10.x.x.x. clients have no issue access the internet and everything thing seems to work fine.
However, I have one client on 10.0.0.51 that is used to connect to a remote VPN site. I cannot connect using VPN. If I add the following statement:
ip nat inside source static 10.0.0.51 interface E0/0
Then VPN works just fine? however you can see that it breaks several other things.
I have tried to put in a static NAT with a specific port mapping for this address but that does not work either. Since I only have one "WAN" address I'm not sure how to get around this.
Any help would be appreciated.
