I have a problem with L2TP / IPSEC in a client, several users connect from the same connection behind a NAT and with L2TP it is impossible, when a user connects, he disconnects the one that is already connected.
I've been reading why this happens and change the L2TP from port strict to port override but still failing
How can I do it? for now I solved the issue by putting one user with PPTP and another with L2TP, but ideally, all users use L2tp
this is the current configuration in the mikrotik
/ppp profile
add change-tcp-mss=yes dns-server=8.8.4.4,8.8.8.8 name="VPNIPSEC" only-one=yes use-upnp=yes
set *FFFFFFFE only-one=yes
/interface l2tp-server server
set enabled=yes use-ipsec=no
/ip ipsec peer
add exchange-mode=main-l2tp generate-policy=port-override passive=yes secret=xxxx
/ppp secret
add local-address=192.168.22.22 name=User password=Pass profile=\
VPNIPSEC remote-address=192.168.22.23 service=l2tp
