I have a sonicwall site to site vpn. At one of the sites there is another Cisco vpn to another site. I need to route the traffic for the cisco vpn through the site to site from the other sonicwall site.
Site A – 10.10.0.0 /16 network
Site B – 192.168.1.0 /24 Sonicwall, A cisco vpn is on 192.168.1.226 address and has routes the 10.10.0.0 network to Site A.
Site C – 192.168.2.0 /24 Sonicwall
Site A-B VPN is working
Site B-C VPN is working
I need to get Site C to transmit the 10.10.0.0 traffic over the VPN to site B and then out the Cisco device.

There are a few things that need to happen.
The Cisco at Site A needs to have a static route added that points to the 192.168.2.0/24 subnet with the site B Cisco as the gateway.
The site B Cisco either needs to have the Sonicwall as its default route or it also needs a static route to the 192.168.2.0/24 network through the 192.168.1.0 Sonicwall.
The site c Sonicwall needs a static route added pointing to the 10.10.0.0/16 network with the site B Sonicwall as the gateway.
