L2TP over IPSEC

RouterOS General
1

HI all,

I can use Android or iPhone to bulid up the L2tp over IPSEC VPN to RB450G v5.24,but I found that if multiple users log-in from the same remote address (in ipsec remote peers),only the last log-in user can use the VPN service.
Anyone can help ?

Sorry…for my bad english.

Check your IP pool, could be that you’re only assigning one IP address and when a new connection is established it takes the IP from that user/device.

In RouterOS, only one IPSec client can connect from the same public IP.

So if you have a NAT router between your clients and your IPSec AC, only one client will be able to connect, as is your problem right now.

Consider using a Site-2-Site tunnel between the sites if you have more clients behind a single NAT router.
