About IPsec
IP Security (IPsec) is the Internet Engineering Task Force (IETF) set of emerging
standards for security services for communications over public networks. The
standards are documented in the IETF Requests for Comments (RFCs) 2401
through 2412. Additional RFCs may be relevant as well.
These standards were developed to ensure secure, private communications for the
remote access, extranet, and intranet virtual private networks (VPNs) used in
enterprise communications. They are the security architecture for the next
generation of IP, called IPv6, but are available for the current IPv4 Internet as
well.
The Nortel Networks implementation of the IETF standards provides network
(layer 3) security services for wide area network (WAN) communications on
Nortel Networks routers.
Note Regarding IPsec and NAT
IPsec and Network Address Translation (NAT) are not supported to work together
on a BayRS platform. NAT or IPsec can process a packet, but not by both. If a
packet matches the NAT source address range, NAT takes precedence over IPsec
and IPsec will not see the packet.
