Sophos XGS WAN Renew Issues

Murphdog

I had an DHCP renew issue at a site today, but I have seen it at others. This one annoys me because I had to drive an hour to the site.

Sophos XGS 87 fed on WAN by FIOS ONT ethernet. Fios rebooted the ONT, because that is what their automated system does when you call in. Lost remote connectivity. Drove in and the WAN interface shows connected with a DHCP IP. Unplugged/plugged the WAN ethernet, no dice. Went into the WAN interface and hit save. It's back. Like I said this is not the first time and I have seen it elsewhere where I have Sophos products. Searching the forums it seems not to be an isolated issue.

Is there not a way that if it can't ping 8.8.8.8 after X seconds force a renew on the WAN?

    I've seen this issue myself this past week and have a ticket open with Sophos support (case# 06370178). I'm not sure they understand what the problem is yet. On my last trip to the remote site on Friday I changed the network cable between my Cradlepoint modem connected to Verizon, and the firewall. The connection has been up all weekend, when last week I was having trouble getting past 24 hours. My symptoms were identical to yours. Like you, the firewall was working but not communicating with wan port and not updating the network port list. It showed it was connected even when it obviously wasn't. I could get it to reconnect by saving the wan connection as you did.
