I need to have my Mac laptop access my LAN from remote wi-fi/mobile networks. The Mac does have "Cisco VPN" capabilities.
I would greatly appreciate a pointer to some cookbook on what needs to be done to set this up. (or some config that works).
Is it correct that Cisco VPN uses port 1723 with the IP/GRE protocol ? How does the router itself intercept incoming GRE connection request ? Via NAT entry pointing to the router's own IP address ?
In terms of authentication, if I already have a minimal radius server on the Cisco, is this enough to authenticate VPN clients ? Or do I need a more sophisticated server on another machine ?
In terms of DHCP, will the router issue the client an IP address, or would DHCP request from the remote client make it to the lan and served by the LAN's own DHCP server ?
