Sorry I originally posted in wrong section.
One bit of bad behavior I've seen in V16, and got burned on again today, is that if you change a key in one tunnel, it also changes the key in any other tunnel using the same key. It is common to use the same key on multiple tunnels and every other firewall keeps them separate. I'm not sure how the XG keeps them separate when they're different, but not when they're the same. When you save the change you get a pop-up saying "This will update the preshared key of all connections configured between the same local and remote peers. Are you sure you want to continue?" Maybe I'm dense, but I read that to mean any extra connections to the same site. All I know is changing one tunnel has been taking down others that had the same key - not nice. When you view the key of the downed tunnel it is indeed the key you made for the other tunnel. This has got to be a bug.
