What External firewall settings for VPS hosting?

[NeilAgg]

Hello:

I am wondering what VPS hosting providers have for their external firewall settings for cPanel VPSs. Right now, I have our external firewall set to block everything except the following:

Inbound:
•cPanel https
•cPanel webmail https
•DNS
•FTP
•HTTP
•HTTPS
•ICMP (e.g. Ping)
•SSH
•WHM https

Outbound:
•DNS
•HTTP
•HTTPS
•NTP
•SSH
•SMTP

Are there any other services I should allow through our external firewall?

Thanks,
Neil

You would probably want to allow:
TCP:
21,22,25,37,43,53,80,443,2087,2089,3306

UDP:
20,53

Here are a few that I don't see in the list but that may be desired:
cPanel WebDisk, 2077
cPanel WebDisk (SSL), 2078
POP, 110
POP (SSL), 995
IMAP, 143
IMAP (SSL): 993

For a more verbose listing I would also reference the following entry in our documentation FAQ: Linux FAQ - Which ports should be open if I'm running my cPanel server behind a firewall?

Check out /etc/services on your server for a list of possible services

(not all of these are actually enabled or in use but gives you an idea)
