Re: ipchains/ip_masq problems

[Greg Wooledge <wooledge@kellnet.com>]

This is in response to a very old message on debian-user which I saw
while browsing the mailing list archives.

I've got IP masq working on a Debian system with kernel 2.1.132 at
home.  I think you're missing the obligatory "echo" for the 2.1.x
kernels to turn on IP forwarding.  I'm not at home right now, but I
seem to recall that in my /etc/init.d/network I inserted the following
lines:

  echo 1 > /proc/sys/net/ipv4/ip_forward
  ipchains -P forward DENY
  ipchains -A forward -j MASQ -s 192.168.2.0/24 -d 0.0.0.0/0

Don't just type these in without double-checking them, though, since
I'm *not* at home and they might be wrong.  If you still need this
information, let me know and I can look it up at home to get it right.
