UPnP & NAT-PMP with Gateway Groups
-
In a Gateway Groups set up for Multi WAN, clients on the network seem to have to pick one WAN IP to create port mapping entries. When WAN 2 is chosen by the Gateway Group, all UPnP & NAT-PMP port mappings fail to work. Clients see WAN 2 as the public IP, but the "Status / UPnP & NAT-PMP" page shows all the mappings associated with WAN 1. Neither WAN responds on the mapped port. Ports mapped manually to WAN 1 in "Firewall / NAT / Port Forward" continue to work fine.
