Hi, after setting up a second EXT connection and Multipath Rules on a friend's firewall, I added a DNAT for the second EXT interface.
I apparently forgot to fill in the "Destination" fields, and saved the rule and turned it on.
It did not warn me that this was an invalid configuration.
Afterwards, all internet access was broken.
Inbound pings worked, but outbound pings and traceroutes from LAN or from the firewall itself all only went out the EXT and returned immediately (they appeared to be working but were only going the first hop).
DNS and all other traffic failed.
Please fix the DNAT dialog so that a misconfiguration with no DEST will generate a warning.
Thank you,
Barry
