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

[Kelly Scroggins]

I've got a Red Hat 5.1 machine with masq running.  I can surf the net until
my hearts content.

I can't use ftp from inside my LAN.  I can login to an ftp server, but I
can't list files. I CAN "pwd" though.

I've decided the problem is with my gateway because I CAN ftp to the same
sites from other locations, like work.

I'm puzzled because I haven't got any firewall rules set up yet (yikes!).  I
can't get them to work.  All I have is an "ALL:ALL" entry in the
/etc/hosts.deny file for now. Which as I stated earlier, hasn't prevented me
from surfing the web or loging into an ftp server.

So I would think that any packets that are returning (ACK bit is set) would
be allowed back in to my network.  And apparently does, with this
exception.  This problem must be unrelated to the issue.

Do you know of anything I could try off hand?

Thanks,
Kelly
