Choice of monitors and/or can't ping modem on 192.168.0.1
-
I have a dual WAN setup and desire to configure failover. My backup WAN is a tiny DSL line through Qwest; unfortunately I cannot find an IP in Qwest's IP space that will serve as a good monitor – anything I can ping from within Qwest space is also ping-able from the outside.
Since I couldn't find a "real" IP to monitor, I decided to go for the DSL modem's internal address of 192.168.0.1. However, psSense can't ping that address, so it too fails as a monitor.
It seems very strange that I cannot ping 192.168.0.1 since it is the address of the DSL modem which serves up the dynamic IP to pfSense on the Opt2 interface. Is there something that I should be doing to allow pfSense to ping this address? Perhaps I need a static route or similar to get it to work? I have a firewall rule that allows any traffic originating on the internal interface to pass to the outside world.
What am I missing? I would dearly like to get 192.168.0.1 set up as a monitor IP for my failover.
Thanks,

Doesn't matter as a static route is created for the monitor ip. It can be tested with traceroute in pfsense gui
imo using the gateway address will be a bad idea. A nearby dns server is what I would recommend.

Thanks Perry – I did indeed have private networks blocked. Stupid user error strikes again...
I am also using a nearby DNS as the monitor.
