I know this can be a dummy's question, but I would like to see if it is possible to find a workaround before to invoke the external provider...
I have a Watchguard running Fireware 10 on my network, and a VNP between the Trusted (10.10.10.0) and the external provider (213.X.X.X). Inside the network we use the VPN to connect a specific software to a SQL 2005 database engine.
I would like to use the same remote database accessing from another DMZ (220.127.116.11).
On the firewall I've created a new rule to address the requests started from 18.104.22.168 to the external provider's IP (213.X.X.X).
It seems (and for sure it is correct) that the traffic is directed trought internet, and not using the VPN.
There is any way to tell the firebox to use the VPN?
Thanks a lot for your advice!
