Cabletron also announced significant VPN enhancements to its current line of SSR 100, 200 and 500 SOHO and branch office routers to support secure VPN tunneling based on IPSec and L2TP. Cabletron is unique in the industry in that its products can deliver VPN solutions over all major "last mile" access technologies, including cable, xDSL, PPP, Frame Relay, ISDN and wireless connections.
SSR 100/200 VPN software: IPSec & L2TP with DES $195 Sep.
However, vendors have combined PPTP with a similar protocol, Cisco Systems' Layer 2 forwarding protocol, to create L2TP
, which supports multiple, simultaneous tunnels for a single client.
The Interworking Function within its Total Control access platform now supports the L2TP
and PPTP tunneling protocols, extending the reach of wired VPNs to mobile workers.
The leading tunneling protocols are: SOCKSv5, Point-to-Point Tunneling Protocol (PPTP), Layer 2 Transport Protocol (L2TP
), and Internet Protocol Security (IPSec).
However, vendors have combined PPTP with a similar protocol, Cisco Systems' Layer 2 Forwarding Protocol, to create L2TP
, which they hope to present to the IETF for consideration as a standard.
The Internet Engineering Task Force has approved a method called L2TP
, which combines Microsoft's Point to Point Tunneling Protocol with Cisco's Layer 2 Forwarding tunneling scheme.
