Hello,
my setup includes two WANs configured for load balancing.
Since updating to 26.1, one of the two works correctly from a routing point of view, but cannot be reached from the outside either via HTTPS or ping.
The firewall rules are correct and identical to those of the other WAN, which works just as well and can be reached from the outside via both HTTPS and ping.
The chipset for both NICs is Intel i225V, and before the update, both were reachable.
If I restart the firewall, the problematic NIC is reachable for a couple of minutes, and then stops responding to ping and HTTPS from the outside, while continuing to work for the connection. Its gateway always remains green.
What could have happened, and how can I fix it?
Many thanks!
26.1 appears to have broken dual NAT. https://forum.opnsense.org/index.php?topic=50571.0
