Hi Tuomo,
It works but only limited to one public ip address.   Same issue as this 
guy's:

https://lists.openswan.org/pipermail/users/2011-February/020126.html

Would you add feature to xl2tpd making it to listen to multiple ips?   
Whenever xl2tpd receives multiple requests, it will fall back to listen 
to the primary public ip only.  It simply ignores request from 
ethernet_ip1, ethernet_ip2, etc.  :((


Faithfully,
Timmy
