Intrazone firewalling


I didn’t realise intrazone firewalling wasn’t possible in Vyatta/VyOS but wanted it working today.

It appears to work fine if a few lines are commented out of the following files:

  • /opt/vyatta/share/vyatta-cfg/templates/zone-policy/zone/node.tag/from/node.def
    — prevents you from commit’ing a zone to zone rule with the same zone name
  • /opt/vyatta/share/perl5/Vyatta/
    — comment out the section that adds an implicit RETURN for intra-zone traffic

After these changes, a zoneX_to_zoneX chain appears to work fine.

Is this desirable by others?


you could easily do this by setting up zone policy firewall rules instead of the in and out rules.
