Hi,
I have a quite simple setup using a RB4011 with two WAN Links (ISP1 and ISP2).
The route table has two entries for 0.0.0.0/0, one with an AD of 1 (ISP1), the other with an AD of 2 (ISP2). I just have that floating route for failover and don't need anything more advanced (load balancing etc.). But there is one problem I want to fix.
I want to monitor my two public IP addresses from the outside, simply by pinging them. While I can easily ping the ISP1 IP while the route is active I can't ping ISP2 IP because the default route (leading back to the source) leads return packets via the other ISP.
So my question is: what packet/connection/route marking and route setup would I need to have packets coming in from one ISP leave the router the same way?
Thanks in advance!
