[NTLUG:Discuss] ftp through RH5.1 masq machine

[David Stokes]

Kelly,

Did you add the ip_masq_ftp module?  Things like FTP, RealAudio and a
few more require modules to be loaded for proper operation.  From the
minihow on IP-Masquerading:

  Then you should add a few lines into your /etc/rc.d/rc.local file
     (or any file you think is appropriate) to load the required
modules
     reside in /lib/modules/2.2.x/ipv4/ automatically during each
     reboot:
               .
               .
               .
       /sbin/depmod -a
       /sbin/modprobe ip_masq_ftp
       /sbin/modprobe ip_masq_raudio
       /sbin/modprobe ip_masq_irc
       (and other modules such as ip_masq_cuseeme, ip_masq_vdolive
        if you have applied the patches)
               .
               .
               .
