vpn traffic between 2 sonicwall firewalls

Posted on 2008-11-11
Last Modified: 2012-05-05
I have 2 sonicwall pro 2040 firewalls in different locations.  VPN client connections to one of the firewalls will allow a user to see resources behind that firewall, but not the other.  The opposite is also true.

sonicwall global vpn client will allow me to have 2 concurrent vpn connections (one for each firewall) to allow me to use the resources behind both firewalls.  is there a way to have the 2 firewall devices talk to each other so that only one global vpn client connection will be needed to allow traffic to route to both firewalls as needed?

    You don't say but i *assume* that as well as the GVPN client connecting in, you have a permanent VPN tunnel between the two units. Or the two LANS are connected via some other method?

    To get the GVPN client to be able to see both local and remote LANS you will need to be careful when setting up the "desination" for each VPN tunnel definition.

    You don't say what OS version you're running. The spefiic details will depend on that.

    right, there is a permanent vpn tunnel between two pro 2040 firewalls, one using sonic os enhanced v4.0.0.. and one using sonic os standard 3.1.5..

    global vpn clients can connect to one or the other, connecting remotely to one does not give access to resources behind the other. (only the one the client is connected to)

    users on either LAN have no problems accessing anything on either side.

    end users are vista clients using global vpn client 4.0

    it might be a moot issue anyway since servers have been migrated and consolidated to the lan behind one firewall.  remote users now do not need connections to both.

    Accepted Solution

    I believe what you are looking for is a site-to-site VPN policy. You would set this policy up on both firewalls and this would enable you to share resources between the two remote subnets. For setup instructions I would refer to the Sonic Enhanced 4.0 administrator guide chapter 41. Here is a link to that guide to the version 4.0; I would assume it's very similar on version 3.0.

    I hope that helps!
