We have a sonicwall NSA 3500, x4 has 2 vlan interfaces so x4:v300 and x4:v301. Each vlan has an IP v300 is 192.168.100.1 and v301 is 192.168.101.1.
I then have x4 connected to a layer 2 only switch configured ports 1-12 v300 and 13-23 v301 and all 23 ports tagged port 24 then port 24 is tagged for v300 and v301.
I added a firewall access rule to allow subnets on v300 to talk to v301 and vice versa but all I can do is ping hosts on either subnet. Nothing else like ssh or http works.
Does anyone have any idea why?
