Sonicwall PRO 2040 intervlan routing for Netgear GSM7248

Posted on 2009-04-02
Last Modified: 2012-05-06
Basically, one port comes down from the firewall to the switch. I have a sub-interface on the firewall for the second vlan. The LAN is on the default vlan and then I have a second vlan. The port that goes to the firewall is in both vlans and tagging is enabled on that port in vlan2. The "access port" that is in vlan2 does not have tagging on it.

What is wrong with this setup?

"Subinterface" is set up how?  I take it you don't mean a separate X1 phyiscal port?

Yeah, Subinterface... It is on one interface (X0)....... ^^^^This was copied from the web interface^^^

Also, right now I am not worried about the routing part. All I really care about is getting vlan2 to be able to communicate with the firewall at all..... Vlan1 can communicate fine. It seems like there is a problem with the tagging....

Both VLANs are tagged?
The Netgear device is supporting BOTH tags on the outside connection?
Is the Netgear passing the tags across or stripping them?
If passing, the Sonicwall is accepting BOTH tags on that interface?

After correcting the "Access ports" VLAN IDs in the Switch >> VLAN >> Port Config section on the web configuration interface. I was able to get the default VLAN and VLAN 2 to work over the link to the firewall.

You didn't really help much, but I am going to give you the points anyway.
