I am currently trying to install IP masquerading at home. I've been
reading the Mini IP Masquerading HOWTO, and I have some questions
which I am hoping someone can answer.
1. The HOWTO says to add the following lines to /etc/rc.d/rc.local:
/sbin/depmod -a
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_raudio
...etc
I presume that under debian I actually just add these modules to
/etc/modules??
2. In my /lib/modules/2.0.36/ipv4 directory I have the following modules:
ip_masq_cuseeme.o ip_masq_irc.o ip_masq_raudio.o
ip_masq_ftp.o ip_masq_quake.o ip_masq_vdolive.o
>From this I am guessing that by installing these modules, I will be able
to run ftp, irc, quake and real audio applications. I am guessing vdolive
is short for "video live"?? And I have no idea about "cuseeme"??
Why isn't "http" here --- doesn't it need a module? What about
"rlogin", "telnet", "ping" and "pop3" (email)??
3. What does "ipv4" stand for? Is it specifically masquerading stuff?
4. The HOWTO says:
IMPORTANT: IP forwarding is disabled by default since 2.0.34
kernels, please make sure you enable it by running
echo "1" > /proc/sys/net/ipv4/ip_forward
This seems a very strange way to enable something. Does it need to be
done at boot time, or when? Why is it done like this?
5. I'm a little bit hazy about what "ipfwadm" does and how it does
it. I imagine as I read further I'll find out, but any enlightening
summaries would be appreciated.
Thanks,
Mark.
