Hi All,
I'm setting up an exchange publishing rule on a TMG2010 EE box but keep getting this error.
<12302 The server denied the specified Uniform Resource Locator (URL). Contact the server administrator>
Looking at the log I can see the destination IP Address isn't the backend CAS server. The destination IP address is the address the listener is bound to.
Source: 49.x.x.x:49313
Destination: 10.0.x.x:443
This TMG box is in a back configuration with two NIC's, one in the LAN and one in the DMZ.
Traffic is NAT'd to the DMZ listener by our appliance perimeter firewall.
Once it hits the TMG box it's denied. My thinking is it's problem with how the "networks" are defined in TMG.
The publishing rule has the CAS server FQDN & IP configured + a hosts file entry & the rule tests out with all green ticks.
Would any kind folk out there be able to provide any insight into why this might occur?
