Have you done a 'cat /proc/sys/net/ipv4/ip_forward' and made sure it
equals '1' ? If not 'echo 1 > /proc/sys/net/ipv4/ip_forward'. This isn't
set automatically by any kernel configuration, and I'm sure if redhat is
doing this necessarily when you turn it on in /etc/sysconfig/network, I
don't use redhat. Its also reset at boot to 0, so make sure your start
scripts are setting this.

So you've made sure all these modules are loaded at the time the linux box
is acting as masq router right (don't trust kerneld for this)?

pppd should be doing this for you. However you managed to muck it up, the
linux ppp machine wouldn't work either so I'm assuming you got it right.

/etc/hosts.allow shouldn't matter for simple network tests like ping and
traceroute.

Otherwise everything looks right.
