PfSense won't ping modem, but network has Internet?

[eiger3970]

Hello, my network briefly lost Internet and I noticed pfSense couldn't ping the modem?

My setup is:
cable modem bridged to pfSense router to pfSense WAN > pfSense router cabled LAN to switch > computers cabled to switch.

I can ping the pfSense router from computers.
I can't ping the modem from computers.

Well if your modem is bridged, what IP would you be trying to ping.  If you modem is online, does your pfsense get its public IP?  Do you mean you can not ping your isp gateway?

So I have a cable modem, which if actually a cable modem would always be in "bridged" mode and only IP on the modem would be 192.168.100.1 ?  is this the IP your trying to ping.  What actual cable modem do you have.  I have the SB6120 for example, its gui interface IP is that 192.168.100.1, and I can ping it from pfsense - even though pfsense has no vip in that network, etc.  You could have a issue if your overlapping the modems IP with one of your lan networks.

So you can see pfsense showing its public IP, and I can ping the modem 100.1 address and the isp gateway on the 24.13.x.x address you can find that IP of your isp gateway with a netstat -rn command
