Firewall Blocked causing daily outages with Linksys router
I have issues since upgrading to Gigabit and getting new gateway Model:CGM4331COM .
I always get Firewall Blocked in logs and it blocks all internet access from my Linksys MR9600 router; which I use as primary connection for all devices. Very annoying and only started when I got new gateway a few months ago. Tech support has not been very helpful. I spent over an hour with one technician on the phone and he pushed a "fix" that bricked the router and I had to get a new one.
I am an IT professional of many years and know how to troubleshoot network issue. I even went so far as to build a network monitor device to track when connections drop (running NEMS on a Raspberry pi). The Internet drops on my Linksys router match the log entries in my Xfi Gateway:
FW.IPv6 FORWARD drop , 6896 Attempts, 2021/8/4 08:13:52 Firewall Blocked
FW.IPv6 INPUT drop , 29453 Attempts, 2021/8/4 08:13:52 Firewall Blocked
I went in and turned off advanced security and disabled both IPv4 and IPv6 firewalls (I have a firewall on Linksys and run client based AV and anti-malware on my devices locally, so this is a non issue).
This is very frustrating because I am dropping Internet 1-2 times a day and the only fix is a hard reset of my Linksys router.
