Hello

I trying to install a L2TP and PPTP VPN with FreeBSD, but I having problems when I connect multiple clients behind a NAT, I would like to know if is possible to create a VPN with multiple client behind a NAT and if is which software can I use

Thanks
 
Where is the NAT? What device is doing the NAT? Where is the server in relation to this? Which L2TP / PPTP implementation on the clients?


NAT introduces a lot of issues.
 
Thanks for the advice and the response.

Right now I'm using a FreeBSD 9.0 firewall/NAT and Mac clients. But my idea is to create a server to allow connections from different type of devices as mac, windows and android. With connections through a different type of routers. Basically a small office with multiple computers that can surf internet though my FreeBSD server. The problem is when two or more devices trying to connect at the same time. The server drops the connections and just 1 can use the VPN without a problem.

I tested with mpd5 and racoon but if you have any other option please let me know I will try it.

Thanks
 
I haven't used MPD for about 8 years, but one thing you will want to ensure is that you have any options for "NAT traversal" turned on, and that you have the relevant ports open on your firewall to enable NAT traversal to work.
