GSM7328Sv2, routing L3 subnets to VPN problem

Hi,

Recently added the switch to an existing 192.168.2 network.

I have configured the switch to have multiple subnets 10.n.1.0/24 with one gateway port on the 192.168.2 network and a default route to the LAN IP of a SonicWall firewall.

On the SonicWall I added a static route from Any to 10.0.0.0/255.0.0.0 pointing to the switch gateway port IP. All of the subnets can see each other and the Internet, and I can connect from outside via the SonicWall VPN to a computer on one of the L3 subnets.

I have a site-site VPN on the SonicWall linking to a 192.168.3 subnet at the other end. Hosts on the 192.168.2 subnet can see it but none of the 10.n subnets can.

What routing setup am I missing?

Thanks

  • because you probably have only 192..x to ip binding when 10. try to connect even static route may allow with one side of the network , table see as coming from other IP in the tunnel and can not trust it .
