We have a SonicWALL NSA 3500, x4 has 2 VLAN interfaces so x4:v300 and x4:v301. Each VLAN has an IP address: v300 is
192.168.100.1, and v301 is
I then have x4 connected to a layer-2-only switch, configured with ports 1-12 v300 and 13-23 v301, and all 23 ports are 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?
