    Thanks Brian I'll give the debug a go

    Sorry, I didn't mean to reply to you persoanlly, so I'll cc this to the
    list in case anyone else out there finds it usefull.

    My command= line was missing only the last " - the gopp script looks
    like this....

    #!/bin/bash
    /usr/bin/sudo /usr/sbin/pppd noauth proxyarp 192.168.0.100:192.168.2.100

    The two IP addresses being what I want the ppp adapters to use.

    (Seems like you've left out the rest of the 'command=' part...)

    It's important that the pppd options match, both on the command
    line and the defaults in /etc/ppp. Make sure pppd is in debug mode
    and check the syslogs to see if you can see what's going on. Also,
    you might want to add a bit of debug stuff in gopp, such as

            #!/bin/sh
            # this is gopp
            DEBUG=/home/vpn/debug.txt
            exec 2>$DEBUG
            echo "Gopp started at "`date` >&2
            echo "Gopp pid is $~ >&2
            echo "Gopp arguments $@" >&2
            ...
            echo "running /usr/bin/pppd arg1 arg2 arg3" >&2
            /usr/bin/pppd arg1 arg2 arg3
            echo "pppd exited with $?" >&2
