Weird Port redirection on 1400

I'm running a 1490 (R77.20.75) centrally managed (R80.10) and have a number of NAT rules for inbound traffic.

One of them is a mail server running in a DMZ, when I want to collect my mail with IMAP or POP3, I use my external DNS name which resolves to the external IP of the FW. Running this on mobile devices should explain the why that is the external IP.

Now we are running into the problem NATting is not done, neither the destination nor the source NAT is taking place. I added an explicit NAT rule for the internal range to the external IP of the FW to be source NATted to the IP of  the GW and the destination to the DMZ server IP.

Log line shows no NAT IP's but the NAT Ruleis showing when you double click the line.


Also when we try to reach a http web page, it is redirected to the gui of the FW itself with the explicit port setup for the Management WebUI.


Anyone seen this behaviour?
