ip_forwarder role should save the iptables rules

[jabl]

As it is, after a reboot of the login node compute nodes cannot access the outside world before one manually runs the playbook which enables ip forwarding.

The iptables rules in ip_forwarder role should be in the {{ ferm_rules_extra }} ansible variable 1 - then ferm will set up the firewall on every reboot. Do you have them in there?

[jabl]

Uh oh, no we don't! Thanks, I'll add them there and we'll see if it works next time we reboot.
