I have a firewall using RH7.1 up and bascially running. This is an upgade from a RH 5.2 system that I have been running for several years. It can do all the normal things, web browsing, email, aim, etc. Real Audio even works. My questions is, I was not able to run the following commands that I had in the 5.2 version:
modprobe ip_masq_irc
modprobe ip_masq_raudio
modprobe ip_masq_ftp

Everything seems to be working expect an interactive game my son plays. It worked under the old firewall but not now. I was thinking that is because I didn't install the moduled listed above but when I try I get the error message "Can't locate module ip_masq_irc" same with the other 2 modules. Basically, the ip_masq_x modules don't seem to be on the system or in the release for that matter expept perhaps in a 6.2 compatability module that I didn't load.

Should I try to install these ip_masq modules? Are they opsolete? If I should use them, where should I get them? Is this the right tree to bark up for the game problem?

My IPCHAINS conf is:

:input ACCEPT
:forward DENY
utput ACCEPT
-A input -s 0/0 -d 0/0 80 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 -i lo -j ACCEPT

you might know this site, but i think you can find some good info on http://www.ipmasq.cjb.net i'd look under advanced firewall rules i think its chapter 6 and http://www.linuxdoc.org/HOWTO/IPCHAINS-HOWTO.html is a nice how-to also

I have read, and am trying to follow, the how-to you list. It is in beta version and a little comfusing as it is not finished and includes occasional statements like "this isn't translated yet, could someone please do that". In any event, maybe I was unclear as when I try to do what the how-to says, I get an error message.

command:
/sbin/modprobe ip_masq_ftp

result:
"Can't locate module ip_masq_ftp"

So, my question is, is this module needed by RedHat 7.1? If so, where do I get it. If not, what substitutes for it.

Specifically, I am working to enable a game that used to work under my RedHat 5.2 firewall.

/sbin/lsmod
type that command on the command line and see if you have ip_masq_module is loaded. (its probably not loaded if it cannot locate it)
and check to see if you can find your answer here:
http://www.europe.redhat.com/documen...e-HOWTO-6.php3
I dont know if the game you are trying to get it to work is there
