Hi,
I have an RV-042 setup for a fail over access. WAN1 is connected to a high speed broadband while WAN2 is connected to a low speed T1 line. WAN1 is the primary interface. Both WAN1 and WAN2 connections have static IPs assigned by the respective ISPs and the same has been setup in the router.
I also have the router firewall setup to pass incoming SSH connections to a server within our network.
Before I start with my problem, let me state that when connecting from within our network to the outside world, the connections happen perfectly fine and if WAN1 fails, it switches over to WAN2. So no complaints there. The problem comes for outside traffic to my network.
Now, from an outside network, when I try to create an SSH connection to the static IP address assigned by the ISP of WAN1, it goes through and the session is stable for as long as needed.
But when I do the same thing for the IP address given by the ISP of the WAN2 connection, the SSH session starts up perfectly fine, I can even login to the server within our network. But the session hangs after about a minute or so.
If I completely remove the RJ45 jack from the WAN1 connection, then the session to the WAN2 remains stable.
Is this the expected behaviour? Am I making any wrong assumptions about my fail over strategy? Or should I switch to the Load Balancer mode to achieve my goals of a redundant mechanism to allow employees to connect to our servers from their home networks using SSH?
Thanks in advance.
Regards
Ayonam
