VLAN cannot connect to internet
VLAN 150 members cannot access the internet. Members of VLAN 150 are on a layer 2 switch with all ports as access ports but port 24 which is trunked to the layer 3 switch. Layer 3 has VLAN 150 added with IP address 192.168.150.2 which is the default gateway of the clients in vlan 150. I also have a default route on the layer 3 switch to the firewall. I have tried to ping the firewall IP and it fails. The interface is configured to allow ping.

I can ping other members on the layer3 switch as well as the switch. VLAN 10 members which are on the layer 3 switch can access the internet and members of 150 can ping members of 10.

The firewall is a Sonic Wall NSA 220. It seems like traffic cannot find its way back from the firewall. I look3ed t the logs and see the following:
Time Date ID Category Priority Message Source Destination

Not sure I would set the vlan on the firewall yet but I definitely seems to be the issue.

can you ping the Layer 3 switch or one of the client connected to it?
