Help running side by side with another solution
We are migrating over to SonicWall but are still using our old firewall/gateway solution as well.
The old system has a virtual interface for a VLAN and all machines on that VLAN are using that as their gateway.
On the new SonicWall system I have added a new virtual interface on the same VLAN with a different IP. PCs on the new system can ping machines still using the old gateway, but they cannot share folders etc.
Is there some sort of routing/access rule that needs putting in place? Or is this just not possible?
