Dear all,

I have RB 150 v 2.9.51 as gateway with NAT masquerade. The problem is that my client can't VPN more than one ip local. If 1 pc connect VPN, the other ip couldn't connect VPN. Any other suggestion?

Thx

I'm assuming you mean clients connecting into your Mikrotik router via a VPN connection?

If so the you need to configure a pool of IP addresses for the VPN service to access.

It's under /ip,pool

Then instead of configuring a local address, specify the pool.

no, my client want to connect to vpn. but there is just one connection. if the one pc already connect, the other one couldn't connect to the vpn. we just vpn client, connect to vpn server.
I have already active ip-firewall-service-ports--> with gre and pptp enable, but it doesn't works. Any idea?

Thx

There is another NAT device prior to the RB150? Maybe a NAT device on the other side (the server side) which isn't fixing up something? Another possibility may be that you have a router somewhere along an asymetric path which is "fixing up" the VPN session in only one direction.
