IPV6 being blocked?
«

I'm getting the following in my Firewall Logs...
lan Oct 25 14:18:44 [fe80::6c3a:297e:xxxx:xxxx]:51968 [2001:470:1:18::125]:80 TCP Default deny rule
My Lan rules are all Defaulted to normal for IPV6
IPv6 * LAN net * * * * Default allow LAN IPv6 to any rule
I'm confused as to why it is blocking IPV6 on the Lan?
I'm running 18.7.6 so freshly upgraded. I had IPV6 turned off on the Lan before because it would stop working after a few days and would have to always wind up rebooting everything to get it to clear up, I figured I would try it after the upgrade and I'm seeing this, I've rebooted the firewall as well as the box I'm trying to connect to.

State tracking drops this traffic because it has not seem the start of the TCP connection. That's where the default rule starts blocking.

If you see it as a firewall issue instead of a client issue with potential security implications -- the client copes with this anyway -- you can disable state tracking in your default IPv6 pass rules under advanced.
