Din nefericire pptp fara GRE nu prea se poate. Adica conform definitiei din wikipedia : "The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets." . Daca ai un numar limitat de hosturi/porturi ce trebuie atinse poti folosi port forward via ssh (putty stie de asa ceva). Poti folosi openvpn (peste udp, sau, mai putin recomandabil, peste tcp). Se poate si ppp over ssh, dar nu pe Windows (sau nu stiu eu cum). Sau poti sa cumperi un ruter pe bune :).
