I’ve been reading the manual, searching the forum, googling, and testing different approaches, but I’m having great difficulty setting up IP Forwarding on a Balance 20 router. If there is any additional documentation on using this feature, a link to that information would be greatly appreciated.
I have a remote site that has 2 connections. One is a dedicated, private line from our home office, and the other is a public line from a different ISP. The objective is to use the private line as our primary link, and use the public line as a failover so local devices have internet access in an emergency. Here are the specifics:
- Router at home office is 10.10.105.1
- Private line is connected to WAN 1 (IP Forwarding mode) with IP 10.10.105.21
- Public line is connected to WAN 2 (NAT)
- Balance LAN IP is 10.10.105.43
- Balance 20 should forward all traffic from WAN 1 to the LAN
- Balance 20 should normally send all outbound traffic from LAN to WAN 1
- In the case there is a service disruption on WAN 1, all outbound internet traffic is sent to WAN 2
When sending a test ping from the System --> Tools --> Ping menu in the Balance, I can hit 10.10.105.1 just fine from WAN 1, but I cannot reach it from the Balance LAN.
From what I’m reading, IP Forwarding should send all traffic from the link on the enabled WAN to the LAN. Am I missing something? Is there a list of requirements that need to be in place for this to work properly?
