Hi,

I am having problems with a L2TP/IPSec VPN. This is my scenario: RouterOS 6.1 on RB2011UAS. I've configured a site-to-site IPSec VPN and a L2TP/IPSec VPN for mobile users. When site-to-site VPN cannot connect the other router for any reason mobile users can't open connection. At that moment, if I disable site-to-site peer, mobile users connect OK.
I've tried assigning port 500 to site-to-site peer and port 501 to mobile peer, but get same result.

Thanks in advance.
