We have an Edmarc 4550 Router, configured with a static IP address, let's say of 18.104.22.168.
DNS settings for our domain associate the name mail.comp.com with 22.214.171.124. When you're out of our network and you try to go to mail.comp.com you are delivered to our router and it sends you to either our mail server (192.168.16.4) or our RDP server (192.168.16.3) depending on the port that you are using.
When internal to our network on 192.168.16.X, our users can't get to the requested service when trying to get to mail.comp.com. We have to use internal host names to make it work. Traffic is being routed to the public port of our Edgemarc, but the router doen't direct the request to the proper host.
Our Edgemarc replaced a Juniper 5GT that had no problem routing things properly internally or externally. What do I need to do to get the Edgemarc to handle this traffic properly?
