We are trying to migrate from a Sonicwall NSA 4600 to a Watchguard. We didn't set up the Sonicwall so we don't have a lot of answers as far as why the sonicwall is setup the way that it is. My question is, there are about 7 interfaces on the sonicwall and no matter what kind of interface it is, the sonicwall seems to have a gateway associated with the interface. If I go to setup a watchguard, the only way I have the option to set a gateway on an interface is if the interface is set to external. I know that not all of these interfaces on the sonicwall are external. In fact, the interface that resembles a "trusted" (LAN) interface even has a gateway on it. If I go to setup a trusted interface on my watchguard, I have no way to assign a gateway. Did the previous user setup the sonicwall incorrectly? Is it possible that I don't need all of these gateways? Thanks in advance.


  • The first question is: Are the gateways real devices? Once you work out what they are doing then you can work out the original design. Alternatively, I prefer to do a "clean slate" approach and design the network for the "now" and not the past. Things that were design considerations when the Sonicwall was installed might not exist any more.
