New ISP Markets

Tunneling Overview

IPsec zIP Security, derived from IPv6 zPackets can have AH (Authentication Header) and ESP (Encapsulating Security Payload) zAH authenticates each packet - data integrity zESP provides privacy - DES (56-bit) or Triple DES (112- bit) zTunnel mode provides private addressing and doesnt require IPsec between end nodes

PPTP - Indian Outhouse

PPTP zPoint-to-Point Tunneling Protocol zDeveloped by Microsoft zUses 40 or 128-bit RC4 encryption zWell integrated into Windows 95 and NT zWell integrated into NT Domains z3rd party implementations available
