L2TP / IPSEC, limited number of users.

[humaxoid]

Hello colleagues! Configured L2TP/IPSEC, but there are restrictions on the number of connections. No more 12 users at one time (or more). Does anyone Have a similar problem? If over this amount, it disables others users.But not all.

@humaxoid
Please check the Number of L2TP Users value
see https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/l2tp-ipsec.html

you can also post /var/etc/l2tp-vpn/mpd.conf for checking

@humaxoid The issue is still present?
How many users can work simultaneously now?

[humaxoid]

@viktor_g
Differently. Usually 12-18 users. If a new user is connected, the other users are drops. But not all of them.

@humaxoid Need more information
Can you attach L2TP service log?

[humaxoid]

@viktor_g L2TP Log file is attached l2tp.txt
I think it depends on the load on the channel, but not on the number of connections. At the now moment, 21 users are connected.
