[QUOTE="wat0114, post: 1035787, member: 91306"] Edge is attempting outbound connection on TCP port 443, IPv6. I don't use Edge, but Firefox, Librewolf and Chrome are all routinely connecting to TCP 443, IPv6. when I randomly open several of my bookmarked sites.I have outbound allowed in UFW (Linux firewall) for port 443, IPv4 and IPv6, and port 80, IPv6 only. Also a couple of IPv4 rules to specific remote IP's for port 80 due to OS update server requirements. These are the rules I have for my web browsers without breaking sites: [code] 443/tcp ALLOW OUT Anywhere 130.61.0.0/16 80/tcp ALLOW OUT Anywhere <===for Linux update server 70.40.0.0/16 80/tcp ALLOW OUT Anywhere <===for Linux update server 443/udp ALLOW OUT Anywhere 8080/tcp (v6) ALLOW OUT Anywhere (v6) 82 (v6) ALLOW OUT Anywhere (v6) 80/tcp (v6) ALLOW OUT Anywhere (v6) 443/tcp (v6) ALLOW OUT Anywhere (v6) 443/udp (v6) ALLOW OUT Anywhere (v6) [/code] [/QUOTE]
