Everything worked up to 3. Now it's OK.

The firewall does that for me. Along with depmod -a and modprobes.

Chain forward (policy DENY):
target     prot opt     source                destination           ports
ACCEPT     all  ------  Linux.CodeHelp       Linux.CodeHelp        n/a
ACCEPT     all  ------  ppp-x-xx.xxxx-x.access.uk.worldonline.com anywhere
        n/a
MASQ       all  ------  192.168.0.0/24       anywhere              n/a        

I'm on extra dumb mode tonight - not enough sleep obviously. I was only 
changing the settings in the temporary installation directory wasn't I!! Doh!

I then commented out the line created by the installer and added the one I 
needed. It works now.

Maybe some day I'll learn my lesson.  So far, I've left an old installation 
in place (/dev/modem/ in LinuxConf - Networking - PPP/SLIP/PLIP), cleared 
that but still left the old modem connection config behind (DrakConf - 
Network and Internet Configuration - modem connection) and edited the right 
config file but in the wrong directory! (And then wondered why the settings 
were being ignored.) Oh and not configured the gateway to actually share the 
connection in the first place (DrakConf - Internet Connection Sharing)!!!!

Time for bed (said Z).

:-)

Now all I need is an auto-dialler!!!!!
