pppd over ssl worked until dreytek ADSL / broadband added to the mix

[Gary Stainburn]

Hi folks.

I've set up another Fedora box as a VPN gateway.  Working locally on the LAN 
everything worked fine. However, I've just installed it now at a remote site 
using that site's Dreytek Vigor ADSL router over a BT broadband and now I 
have a problem with the pppd connection constantly dropping / raising.

The pppd link is raised using the following:

/usr/sbin/pppd updetach noauth passive \
    pty "ssh $HOST -P -o Batchmode=yes /usr/sbin/pppd nodetach notty noauth" \
    $LocIP:$RemIP

Which worked before and still does. However, as the /var/log/messages extract 
shows, there is definitely a problem.

Can anyone suggest what I need to do to fix it.
