firstly i do appologise for posting yet again with this, however i do seem to have got a little bit closer to the issue. I just dont seem to be able to fix it:(
Here is the explanation ....
At the Main Office we have a Cisco 2600 Router (IOS 12.3). A Remote Site has a Linksys Router and this connects to the Main office Cisco by an IP Sec Tunnel (Site-To-Site VPN).
All works fine’ish
On the Cisco:
18.104.22.168 Nat’s to 192.168.0.10 (A Small Business Server)
22.214.171.124 Nat’s to 192.168.0.12 (A VoIP Server)
Both networks can ping everything on each other’s network addresses
192.168.0.10 also hosts a PPTP server which has now broken. From the 192.168.0.10 Server when I go to www.whatsmyip.org it is showing as the Routers IP (126.96.36.199) and not the natted address of the server (188.8.131.52).
If I change the following lines in config from:
ip nat inside source static 192.168.0.10 184.108.40.206 route-map nonat
ip nat inside source static 192.168.0.12 220.127.116.11 route-map nonat
ip nat inside source static 192.168.0.10 18.104.22.168
ip nat inside source static 192.168.0.12 22.214.171.124
then go to www.whatsmyip.org it is showing at 126.96.36.199. The only problem with that is that the remote network (192.168.254.0) now cannot ping or access 192.168.0.10, or 192.168.0.12 because it is been natted with all traffic.
I know that the PPTP VPN cannot be estabished as the GRE tunnle cannot come up. It see's traffic coming in from 188.8.131.52 and not 184.108.40.206.
Hope the above makes a bit of sense, and not just the rambling of a mad man?
Any got any idea’s, about 5 weeks on this now and seriously starting to loose the little sanity I had?
