Gary, Good to hear you are making some process.  So if you ping from
Iserver now, does diald establish your dialup connection?

The article is a little dated and the method for enabling IP forwarding
is different in RH6.2.  Try adding the following to where you start
diald (/etc/rc.d/rc.local ???)

echo "1" > /proc/sys/net/ipv4/ip_forward

Is your ipchains set up?  As a start you could try the following

/sbin/ipchains -F 
/sbin/ipchains -A forward -j MASQ -s 192.168.1.0/24 -d 0.0.0.0/0

In the same place you do the echo

Hope that helps

Cheers,
Rod
