Are you sure that your uClinux system can actually handle the load of the 
VPN encryption? If it doesn't have a hardware crypto chip then I'd be very 
wary of it.

And you might just want to make your own life easier - and not use the 
appliance for the VPN endpoint, but something else - e.g. Draytek 2820 (or 
a 2900 equivalent) and then the clients can use bog-standard Microsoft 
pptp. You might save yourself a whole load of grief that way.
