Greetings i have two servers behind the router and a block of 6 external addresses on which incomming connections can come in on.

Im trying to forward all ports on two on the external IP addresses to the internal servers which both have two network cards running ISA.

Ive configured the following rules.

ip nat source static 10.0.0.2 **.***.**.***
ip nat source static 10.0.0.3 **.***.**.***
ip nat inside source list 3 interface Dialer0 overload


access-list 100 permit ip any host **.***.**.*** (These IP's Match the NAT statements)
access-list 100 permit ip any host **.***.**.***

access-list 3 permit 10.0.0.0 0.0.0.255


Unfortunately i cannot get to services on the inside of the router, i have tried stripping the server down to just a network card but am having no luck.

Any suggestions would be much appreciated.
 
ip nat inside and ip nat outside statements on respective interfaces? Also make sure that the host address in your access-list is the public address, not the 10.x.x.x address.
It should be "ip nat inside source static x.x.x.x x.x.x.x" too.
Could you post a more complete config up?
