Hi,
I have a cisco 2811 router with 2 wan ethernet ports and 4 lan ethernet ports, 2 internet connections (1 is FTTC (vdsl) connection so I configured pppoe dialer and 2 is Virgin media connection to the VM router so its simple ethernet connection with static public ip address) , both connections works fine.
I configured local network with NAT on FTTC connection (tried it on VM as well) and that workes fine as well.
What I am trying to achive is use wan1 (fttc) connection by default for NAT and if it goes down - switch to wan2 automaticaly.
Idealy I would need to have part of local network to be NATing to wan1 and, if wan1 goes down, failover to wan2 and other part of local network to NAT to wan2 and, if wan2 goes down, to failover to wan1.
Router details: Version 12.4(13r)T
Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(12), RELEASE SOFTWARE (fc1)
System image file is "flash:c2800nm-advipservicesk9-mz.124-12.bin"
I configured the router as in example below using route maps and track command and the issue is that dialer (wan1 fttc connection) goes down, it swithes over to wan2 and doesnt go back to wan1 (dialer), its just doesnt dial fttc connection.
this is my config:
