Maybe http://openvpn.net/ ? With OpenVPN, you can: * tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port, * configure a scalable, load-balanced VPN server farm using one or more machines which can handle thousands of dynamic connections from incoming VPN clients, * use all of the encryption, authentication, and certification features of the OpenSSL library to protect your private network traffic as it transits the internet, * use any cipher, key size, or HMAC digest (for datagram integrity checking) supported by the OpenSSL library, * choose between static-key based conventional encryption or certificate-based public key encryption, * use static, pre-shared keys or TLS-based dynamic key exchange, * use real-time adaptive link compression and traffic-shaping to manage link bandwidth utilization, * tunnel networks whose public endpoints are dynamic such as DHCP or dial-in clients, * tunnel networks through connection-oriented stateful firewalls without having to use explicit firewall rules, * tunnel networks over NAT, * create secure ethernet bridges using virtual tap devices, and * control OpenVPN using a GUI on Windows or Mac OS X. Haven't used it myself. But had references who swear it works well. - Sandip _______________________________________________ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22/23, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
