Look up the command line options: I can't remember, but I would suspect
'route add default gw device ippp0' would be the correct command?

Won't work if you haven't exported those variables

> 2/   /sbin/route add default gw $194.247.47.47 dev $ippp0

Won't work cos you've prefixed the ip address with a dollar sign.

> 3/   /sbin/route add default gw $REMOTEIP dev $ippp0

Won't work because you may not have exported the variable and you've
prefixed the interface with a $.

> 4/   /sbin/route add default netmask 0 ippp0

Won't work cos I don't think that's a valid request; check command line
options.

> 5/   route add default netmask 0 ippp0

I suspect 'which route' is /sbin/route, so 5 == 4, and hence still doesn't
work.

Not surprising, route probably soldiered on and gave you a nonsense routing
table.

Are you using ip masquerading? If not, the machine at the other end is
probably throwing all your packets in the bin.

Cheers,
