Troubleshooting inoperable tunnels using zone bridging.
I have set up and connected my tunnels and they all show to be open, but I cannot send traffic down the tunnel.
This issue may be caused by firewall rules rules not being set up between the originating interface and the IPSEC or L2TP Interface.
If your Smoothwall is running the Inverness release or later, you create zone bridging rules in the Firewall page (Network > Firewall > Firewall rules). Our knowledge base article, How do I create a Zone Bridging Rule in the New Firewall?, provides a detailed description.
