I have an HP V1910-48G and SonicWALL TZ 105 set up with two VLANs that should be able to reach the Internet but they cannot.

My network configuration:

VLAN 1 - - Transport Network

VLAN 50 - - Infrastructure 1 (Ideally can reach and be reached from Internet)

VLAN 100 - - Infrastructure 2 (Ideally can reach and be reached from Internet) - SonicWALL LAN interface - Switch VLAN interface - Switch VLAN interface - Switch VLAN interface

The odd thing is that a client in one of the infrastructure networks, say, can ping every VLAN interface i.e.,, but cannot ping the SonicWALL at Even stranger is that using the diagnostic tools on both the SonicWALL and the Switch, I can ping both devices from eachother i.e. SonicWALL can ping and Switch can ping So I know there is connectivity.

It seems as if the issue is either my VLAN membership/tagging configuration or routing configuration on the HP Switch or a combination of the two.

Any ideas?
