Site-to-site VPN behind other firewall

[Gilberto Ferreira]

Hello guys

A certain customer ask me to create a VPN tunnel between two separted networks...
But, unfortunately, he can discard their current Firewall...

This said, I was imagine to create a following scenario:

1 - A Zentyal Server installed inside the Company One, act just as a VPN Server, not as a gateway
2 - A Zentyal Server installed inside the Company Two, act as a Gateway

Then I wanna install OpenVPN service on Zentyal inside the Company One and create some rules over current firewall, to open communication between Internet and Zentyal Server...

On Company Two, create a Tunnel using VPN services to Zentyal VPN Server inside Company One...


This can be done???

Thanks a lot

I can't understand why Zentyal doesn't work...

I suppose Zentyal exist to turn your life admin better... But this don't work!

I try set up a VPN between two Zentyal Server 3.4 and although I can get  a connection, I am unable to ping or access both side...

So, I remove everything related Zentyal and keep just the Ubuntu System, set up a VPN on hand and everything works properly...

I am really really sorry... But I am about to leave Zentyal Server.... So sad!
