Can a Sophos UTM be used as a VPN Gateway from behind a NAT?

Hello, long time reader, first time poster.

Situation:
I am a Network Administrator for a company and attached is a photo of both our MPLS and Internet. So, naturally we are completely down. This includes our PRI and POTS lines.


Although we use Cisco ASA's at all of our 6 sites, I am a huge UTM fan. I talked my manager into loading a UTM on a PC, and hanging 3 Air Cards on it, and load balancing them. While the stability of the cards leaves room for improvement, it does function.

Next I need to setup 2 VPNs. Site2Site is out because the Air Cards have me behind a NAT. I have used the client/server SSL VPN between 2 UTMs in the past, but this is the only UTM available.

My question is this;
Is there a way to use the UTM as a VPN Gateway to an ASA from behind a NAT?

The ASA's I need to connect to do have client VPNs setup. Not sure if this will solve the issue.

Thank you for taking the time to read this post.

  • The server that the ASA runs for Cisco clients is comparable to the one the UTM runs in 'Remote Access' for Cisco clients, so that won't be of much help.  The situation is very similar though.

    Cheers - Bob
