A few UFW tidbits

Here are some of the common UFW rule management commands that I seem to always forget...

1. View rules in numbered format:
   sudo ufw status numbered
2. Add an allow rule with comment:
   sudo ufw allow from <IP> to any port <#> comment "Comment goes here"
3. Add an deny rule with comment:
   sudo ufw deny from <IP> to any port <#> comment "Comment goes here"
4. Add an deny rule to all ports:
   sudo ufw deny from <IP> to any
5. Insert a rule at the head of the rule chain:
   sudo ufw insert 1 deny from <IP> to any port <#>
6. Delete a rule (usually after viewing numbered rules):
   sudo ufw delete <#>
