But for your above example, can double-quotes around tcp be inside double quotes for the whole thing? It's many years since I did personal firewall rules. Back then it was iptables, I'd made a script with all the rules I wanted. Going from memory, it started off with an isolation command (didn't want things sneaking it while it's pants were down), cleared all the existing rules, put in my rules, and then the network was allowed to pass traffic. When needed, I did any needed changes in my script, and ran it. It was the best way I could think of to always get consistent results. -- uname -rsvp Linux 3.10.0-1160.90.1.el7.x86_64 #1 SMP Thu May 4 15:21:22 UTC 2023 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
