Untangle firewall common ports to unblock
If you are setting up an Untangle firewall and want to use it at your house or business but might not know common ports to allow, here is a list. I have things a bit tighter at work but at the house I like to have instant messengers etc working.
Skype TCP ports 13861, 34954, 42045
Apple remote admin stuff – tcp 5354
typical email – tcp 25, 143, 465, 587, 993, 995 (use these at your own risk. Some you need for gmail etc, but if you open 25 outbound you may be spamming if a machine is owned)
web – tcp 80, 443
openvpn – tcp 1194
ssh – tcp 22
ftp -tcp 21
Instant messengers – tcp 1863, 5050, 5190, 5222, 5223
Remote desktop – do some port forwarding so it comes in on like 10020 and goes in to 3389. Dont open 3389 to the outside.
How do you find more?
Open a command prompt
type in netstat -no and hit enter
you will see a list of the open source and destination addresses. Compare this list to the auto refresh block list in your untangle firewall. Look for the PID. Compare that to a task manager PID and see what process is using it. Make sure you know what you are allowing when it is blocked.
