Multiple L2TP/IPsec sessions from one WAN IP

RouterOS Beginner Basics
1

Hi all,

I successfully managed to configure L2TP/IPsec server and I’m able to connect to the server using VPN client. The server is in the office, and I’m at home when I try to connect my PC I’m able to get into the office network, but when I connect another device (e.g. iPhone/iPad) or PC, the first session (my Laptop) getting terminated. This is strange, don’t know why I’m not able to connect multiple clients from my home to Mikrotik at office using L2TP/IPsec. Is this normal? or there is a fix? BTW the current version I’m using is 5.18.

Thanks.

Hi Sir
maybe it’s a license issue. If you have a Free Level RouterOS license, the maximum number of L2TP concurrent tunnels is 1.

another check is to use different l2tp accounts and assign to each one differents remote ip
under /ppp secret


If this doesn’t help , share the configuration so we can locally reproduce the behaviour.

mooreover did you mind to send the output of the ppp l2tp debug related to mirkrotik l2tp server?


have a nice day and let me know
