searching the forums for "LCP: timeout sending Config-Requests" could be a good start, as the same question as been posted many times

These are normally due to the GRE protocol (47) being blocked or not correctly forwarded due to your firewall, make sure your firewall are forwarding the correct ports/protocols.

Have a look at this:

Indeed, opening up GRE port 47 (tcp/udp) resolved the issue.

Thanks all.
