Thank you. &nbsp;Worked like a charm.

<div>
you're welcome...thanks for the points!

<div class="content wysiwyg-content">
Our office is using a Sonicwall NSA 240 (site A) has a VPN to a hosted server (site B). &nbsp;We have a vendor (site C) that needs access to the server at site B but that host won't allow secondary tunnels for vendors. &nbsp;<br />
<br />
My host at site B said I would have to create a tunnel between A and C, then route the VPN traffic to B. &nbsp;I have already established the vpn beteween A and C. &nbsp;Do I just have to add the Site C local network to the site A-B VPN config or will I need to add static routes?<br />
<br />
I don't have access to either B or C firewalls and will have to ask each side to make changes separately if needed. &nbsp;If it would help, I believe the host at Site B is using a Cisco ASA, don't know about Site C hardware.

Routing between VPNs on Sonicwall

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

Internet Protocol Security

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
