Playing online games through my university firewall/router

I am trying to play Joint Operations online and am unable to do so. I am connected to the internet via the universities LAN. I've spoken to the techs here and they say the only ports that are being blocked by their firewall are 25 and 80 (for HTTP I'm using the universities proxy). This is what Novaworld's techs said:

"If you have a Router or Firewall you will need to open the Ports 32768, 49152, 64206, 7597 type UDP in the port forwarding ranges."

I also am unable to ping any address that isn't local when using cmd prompt (timeout), what could be the reason for the timeouts? what type of pings are sent out when you use DOS?

The following e-mail information may be usefull to anyone trying to help me:

> Here is the information you requested:

> The port the game uses to connect is 64206.
> DNS server is 194.72.9.38(when connecting to novaworld)
> and 208.231.90.240 to connect to game servers.
> As for online documentation, I couldn't find anything specific to
> this problem.

Does this now work?

I have established that connections to port 64206 can now be
successfully made out of the University and thanks to my colleague I
think we've found the problem that was originally preventing this.
ResNet uses private IP addresses that are only valid within the
University network. The main University firewall translates these into
addresses that can be contacted in the outside world, recording the
ongoing connections in a table that can be looked up when replies need
to be sent back to the originating computer. After clearing this table
connections to port 64206 were possible.

This means you would need to have the University config their firewall to forward these ports to your private IP.  (not likely going to happen)  

Roughly what sounds to me is going on ... When you connect to the game this takes place on port 64206 outgoing.  The game server then turns around and sends data back to you on ports 32768, 49152, 64206, 7597.  The University firewall has no idea who to send these packets to internally, hence the need to forward ports 32768, 49152, 64206, 7597 to your internal IP.

"I also am unable to ping any address that isn't local when using cmd prompt (timeout), what could be the reason for the timeouts?"

Most likely the University firewall is set to deny ICMP.  If you cannot ping outside the local network, odds are pretty good that no one outside the network could ping the University firewall IP either.
