We have had the RV042 router a bit more than a year now and it has been connected over PPPoE and WAN1 port to a a BT Fibre line.
Recently we had to change and start using the WAN2 port. WAN1 port stopped working and the software did not even allow us to save the correct PPPoE username and password again as it kept changing to 'END' and kept sending that over to BT to connect.
Ever since we started using WAN2 the one to one NAT seems to have stopped working. Are there any limitations with one to one NAT and the WAN2 port? DMZ is disabled as it has always been.
Any help would be greatly appreciated.
