In the past I have had no problems handling static one to one NAT mappings along with IPSEC VPNs. However, in trying to do TCP port mappings, the standard way of delaing with the static mappings is not working, the internal server that has the NAT mapping can no longer communicate out to the Internet. Can anyone tell me what is wrong with the below config that has TCP port mappings?
My first guess is I need to kill the line in 107 denying Dynamic NAT since I want the server to be able to establish outbound connections on any port. But Will it conflict with the static port mappings ?
Here is the NAT portion of the config::
ip nat inside source list 107 interface Ethernet0/0 overload
