Some source nat rules don't work

I have multiple source nat rules to nat certain servers to different public ip addresses. Most of the rules are working but I am having issues where some just don't work. I have tried deleting and creating them and still have issues. Also, my main source nat rule will randomly stop passing traffic for about 15-20 seconds and then resume. I know its not the internet connection as everything was working fine on our Sonicwall.

Anyone else had weird source nat problems?

Hey Josh Kaufman

Sorry to hear about the issues you've been experiencing. More investigation would be needed to take a look at your rules and this traffic. Have you tried performing a packet capture on your XG to discover which firewall rule is applying to your server traffic when this issue occurs? Is it possible that your firewall rules are configured in a way where potentially 2 rules are conflicting and traffic is being matched with unexpected results?
