L2TP VPN and udp tracker

[laf23]

Hi,

here's my problem. I'm using a VPN that has two protocoles. I have the same VPN set up in PPTP and I can also connect it in L2TP.

When I use PPTP, the torrent start faster and UDP trackers seems to work (It says so).

When I use L2TP, the UDP trackes tells "connection timed out". And the torrent is slow to start. (peers exchange works, see the screen)

Anyways, I still get good speed but It takes a lot of time to get to It.

Is there something I can do ?

Thanks a lot !
