Title: Can't get SNAT to work Post by: TheEricHarris on Thursday 30 December 2010, 05:52:44 pm Rules that were imported from a backup work fine in my 2.4.1 box. But if I try to create a new rule, it doesn't work. I need SNAT to work. I can get port forwarding to work when my server uses ENDIAN as it's default gateway, but that is not what I want.
In the previous version, there was a checkbox for SNAT and it automatically created the SNAT rules. I've tried to manually create it and it doesn't work. Anyone having this same issue? Is there a workaround? Title: Re: Can't get SNAT to work Post by: TheEricHarris on Friday 31 December 2010, 04:01:07 am Here is some more info.
I have two Endian Firewalls: 172.30.100.100 and 172.30.100.200 .100 is my primary firewall that is the default gateway in my level3 switch, so all outbound traffic goes through this. I am trying to port forward an external IP (70.10.10.10) with port 443 to my Exchange server (172.30.100.31) on my secondary firewall (172.30.100.200). So for this to work, I need to use SNAT because the traffic is coming in from the firewall that is not the default gateway. I've had this working 2.2 with no issues.

In this test, I'm trying to get http://72.16.139.50:80 to port forward to 172.30.100.40:80. SNAT does not work. The Default GW on 172.30.100.40 is set to another Endian firewall box.

Oh well!
