We have a remote Hosted Web Application in a server with IP address 80.241.209.xx
Our Network is behind a Watchguard XTM 505 with OS 1.7.
Our Exchange 2010 Server has a Private IP, 150.81.1.x and has a 1-1 NAT with one external interface which its Ip is 146.198.136.xx in which the server responds to DNS. The smptp packet filtering works perfectly for inbound and outbound smtp traffic.
Now the problem is that I want this application to send email to external addresses through the exchange server. I already created the receive connector on Exchange that has in the remote address the 80.241.209.xx. The Authentication is Externally secured using IPSec as per instructions and the permitions is Exchange Servers and Anonymous users.
While I telnet from 80.241.209.xx to mail.avratours.gr port 25 which responds in 146.198.136.xx I can send email only to internal users and not to external addresses.
Can I do something by creationg a policy in watchguard?
