Hi @hizibiz 

Thanks for posting in our business forum.

Please be specific about the symptom you have with the router while the second WAN is active.

Have you considered that the other WAN may be using HTTP, HTTPS, and SSH causing a problem in accessing the 80 443, and 22? This is a generic ask because I don't know what symptoms and behavior you experienced on the router.

I expect to see more details about your specific setup and configs on this port forwarding and second WAN.

  @Clive_A  Here is short network diagram. 

 

With 2 active WAN connections, attempt to access the public IP on WAN/LAN1 port over http / https / ssh from external network times out. 

 

The same connection attempt perfectly works ( response 200 for http / https and login prompt for ssh ) when WAN1 is down / disconnected. By works means, the connection gets DNAT'd to the IP reserved host (on private IP subnet which has all internal hosts) with http / https / ssh open.

 

WAN1 is a path to another router terminating a fibre connection over another private subnet. It does not have any other host.

 

The same config perfectly work for TL407.

Can you upload a backup of your file of ER605? Get a .txt with your username and password and your backup in one compressed package. Zip them and use the email address you registered on our forum as the password. I need to reproduce this with our test team.
