I am using dual homing for internet connection.
I want to force all traffic from the LAN to access the internet via Router #1 while Router #2 is a backup.
I want to track TCP port 6000 (communication between a certain host on the internet talking to a certain PC on the LAN) and in case TCP port 6000 is down, to route the traffic between them via Router #2.
This is the only traffic passing between the LAN and the host on the internet.
Now I have two static routing lines configured with different cost.
I want to use IP SLA, tracking TCP port 6000 and switch to the backup Router in case TCP port 6000 is down.
Can some one post a simple configuration to do so?
