I would like to configure an ipsec vpn tunnel to another company running a cisco asa 5510. Our mikrotik is already configured for what appears to be pptp. Can someone lead me in the right direction or give me some some steps I need to go through to get this done? I would like the following:

1. A new internal subnet created that isolates the VPN tunnel to only that subnet
2. An addition WAN IP added to route the ipsec VPN traffic

Here is my current config from winbox:
