How to Block Access to Ventrilo Server

My son uses Ventrilo for online gaming, however, there is one server I would like to block his access to because it's a bit..."mature" for him. I have the IP address of the server as well as the port, I wonder if it would be possible to block it via the router, or the firewall running on his PC. The router is a Linksys and the current firewall is ZoneAlarm. I wouldn't be against changing to another firewall if that is necessary.
 
If you are running windows xp, you can:

Open the folder windows\system32\drivers\etc
Open the "Hosts" file using notepad
There should already be an entry of "127.0.0.1 localhost" in there
Just type in "<ip address of vent server> localhost" (without quotes)
If you have the dns address of the server then type "127.0.0.1 <server name>" (again without quotes)

This will prevent his computer from accessing that server.
 
Hrmm, tried it with no luck. Found the file and added this entry (without quotes of course) underneath the localhost line. Saved and rebooted for good measure but the computer still seems to be able to access the server without a hitch.
 
I apologize, that file will block only if you know the dns name, not the IP address. You should be able to block that specific port within your Linksys router. I have a linksys (Model wrt54gs) that will block certain ports. It's under the Access Restrictions area. Let me know if you need help setting that up.

Also, you can remove that entry from the Hosts file.
 
Tried blocking the port, again no luck, but I could be doing it wrong. I looked over the Access Restrictions portion and added a blocked service with the TCP & UDP protocol (guessed on that part) and set the port range as the server's port. Is there anyway I could look up the DNS name of this server?

EDIT: I Googled resolving a DNS name from an IP address and found a few sites that would do it, plugging the IP address I have in though didn't return anything so guessing that won't work.
 
I tried it first without messing with the scheduling portion of the page or the "Internet Access Policy". I just added the blocked services portion. When that didn't work I created a policy and added his computer to the list of PCs thinking that the two sections of the page might be tied to each other. The IP is 66.207.162.50
 
I forgot to ask, is it on the standard vent port? (3784) Does he use other vent servers on this port also? Because if he does it will block access to those servers as well.
 
No, it seems to be a unique port number, at least unique enough that I've never seen it on any other servers.
 
Actually it worked like a charm! I just unplugged the router for a bit to restart it and when everything reconnected it seems to be working just fine. Thanks a ton!

EDIT: If you, or anybody else for that matter, happen to think of a way to block the specific IP address I'd appreciate it also. Just in case anything ever comes up that might need to use that port.

On Windows XP, there's a utility known as NSLOOKUP (run->cmd) and then enter
nslookup www.google.com -> 74.125.19.47
nslookup 74.125.19.47 -> cf-in-f47.google.com​
works both ways :)
