My point is, that if your system has iptables rules, you're responsible
for maintaining them. A default Ubuntu install doesn't install a
firewall of any kind. On a default Ubuntu install, you don't have the
GRE protocol blocked.
If you are behind a firewall, or run one on your machine, it is your
responsibility to configure it correctly. Because Firestarter is
blocking GRE, it also needs to be configured to allow it for machines
you wish to connect to.
While it might be a feature enhancement to have the VPN add rules to the
firewall dynamically, it is certainly not 'expected behaviour' and not
performed by any of the other VPN packages for NM.
I am reassigning this bug to firestarter, as people involved with that
package may be able to help you.
