Hello everyone,
I’m having a few issues with some services. I have a few NAT rules for VNC and RDP connections which work flawlessly and a few others that end up being matched by the forward filter invalid drop rule. VNC on ports 6001 and RDP on port 3389 work ok but nat rules for ports 81, 8443 (ssl) start fine but then get matched and dropped by the forward invalid drop rule.
All this services run on different vlans. What could be the cause for the web based services to start fine but then get matched by a drop rule in the forward chain for invalid traffic.
