we have some problems with vpn l2tp/ipsec: when more clients connect vpn from same network to the same remote network, 1 client at time can work. The other cannot reach the remote network. One client at a time can work for a while, then another client starts to work for a while, then another and so on.
1) It's a configuration problem?
2) Or it's a problem with the structure of the protocol (so we can not do anything ...)?
3) Or a problem with RouterOS? In this case do you think it can be resolved shortly in the next releases?
