Topic: ip masquerading

[Will Price]

Like e-smith, pretty cool just playing with it at home right now. Works great, just one little problem. Messing around with some online games (heat.net for one), but having some problems. Worked it out to the point that I know some of the ports (47624 with the range 2300-2400) must be open for inbound and outbound tcp and udp traffic. Other games have other ports that need to be open. Any good way to do this and what do I need to modify to open it up? Greatly appreciate any ideas.

Thanks!

I faced a similiar problem,  wanting to be able to ftp into a machine behind the firewall.  Download the rpm ipmasqadm,  install it and read the man page.  It will require the insertion of a new rule into the ipchains rule set.  You can specify which port to open and which machine to route the traffic to.  Just realize that the more ports you open,  the more potential holes you reveal to those unsaviour types who get incredibly happiness out of breaking stuff.  Also,  you will need to know what ports to allow access to,  and where to forward the appropraite packets.  The rpm can be gotten from any of the redhat mirrors,  http://www.redhat.com/mirrors.html.  Just drag it onto an ebay,  telnet in and rpm -Uvh the file.  then man ipmasqadm.
