Hi,

I think you're missing rule accepting traffic entering VPN
connection interface.

Try adding ACCEPT in INPUT or MARK 0x1 in PREROUTING for udp dport
1701. Alternatively you can MARK/ACCEPT incomming traffic on VPN
interface (eg. tap0 - vpn interface, then -i tap0).

The same will apply to traffic comming on l2tp interface if you going to
terminate the connection on very same box.

Hope that helps.

Regards,
Marek
