GRE tunnel through firewall

Hello all,

I am trying to setup a GRE tunnel between 2 routers, one of which is located behind an Astaro firewall. I have setup NAT and packet filter rules on the firewall to pass all GRE traffic into the router on the inside of the firewall. As a test I also setup the rules to allow ALL traffic to pass to the inside router. Anyone successfully done something like this?

Once I tried a similar setup with a somewhat old release of astaro with no luck at all, maybe a more recent release does support natting of gre tunnels. Bye, Tosh.
