Sonicwall NSA 2600 X0, X2 X3 Etc on same subnet

Is there a way to configure all the ports except X1 to be on the same subnet? With lower-end Sonciwalls this is pretty easy with port shielding. I have a switch attached to X0 but would like to use the additional ports on the router also. right now each is configured to a different subnet. I'm assuming I can create firewall rules so I can see everything between subnets but would prefer them all on the same network. L2 bridging does not work with DHCP and only works with one additional port.

Which version of firmware is on your NSA?

Are all of the interfaces configured to be members of the LAN zone already?

yes all are in the lan zone now with different IP X0 X2 X3 etc....
The more I've checked around, the more it appears you cannot do it. Even checking in forums produced one article citing that Sonicwall's justification was to push a lot of that work off to switches. Which sounds very odd given that TZ devices kept the PortShield feature. If there's indeed some other way of doing it, you may want to check with Sonicwall support directly, but I think it will be a fruitless search. Worth a shot nonetheless.

Thanks, that's what I found too. I gave up and will just set up different subnets on the ports these are used for test most of the time anyway
