Hi, I recently changed our router to a cisco 877, the exchange/owa Server and port used have not changed. I added the NAT and acl for owa to the new router. all other NAT and ACL are working fine and are similar to my OWA entry. I've checked IIS /exchweb and made sure to uncheck SSL. I am not using the defauilt port. This is set to 8081.

ip nat inside source static tcp xxx.xxx.xxx.7 interface Dialer0 8081
.
.
.

access-list 101 permit ip any host xxx.xxx.xxx.7
access-list 101 permit tcp any any eq www
access-list 101 permit tcp any any eq 22
access-list 101 permit tcp any any eq 8081

Has anybody experienced this issue berfore? any comments/suggestions greatly accepted. NAT and ACL also included in CODE: section
ip http server
ip http access-class 2
ip http authentication local
ip http secure-server
ip http timeout-policy idle 60 life 86400 requests 10000
ip dns server
ip nat inside source list 1 interface Dialer0 overload
ip nat inside source static tcp xxx.xxx.xxx.7 interface Dialer0 25
ip nat inside source static tcp xxx.xxx.xxx.6 interface Dialer0 21

ip nat inside source static tcp xxx.xxx.xxx.6 interface Dialer0 22
ip nat inside source static tcp xxx.xxx.xxx.7 interface Dialer0 8081

OWA doesn't like using other ports. I have never had much success on using a port other than 80 and 443. If you want to use any other feature like RPC over HTTPS, or Exchange ActiveSync then you must use the native port as they are hard coded to those ports.

Thanks guy's
I can telnet to port 8081 internally but not externally.
We use the url http://xxx.xxx.xxx.7:8081/exchange. Works ok internally.
same format when using the external IP address. I think it would be a ACL issue?

I have it working now. I think your right about using other than default. I added another public IP address to the router and changed OWA to use the default. Worked straight away. still confused why it worked with the old router.... :-)
