    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?

    Thanks

    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.
