Netopia 6.3 manual Pfs-Dh

Appendix B

Peer Internal IP Network	The Peer Internal IP Network is the private, or Local Area Network
	(LAN) address of the remote gateway or VPN Server you are communi-
	cating with.
Peer Internal IP Netmask	The Peer Internal IP Netmask is the subnet mask of the Peer Internal IP
	Network.
PFS-DH	Perfect Forward Secrecy Diffie Hellman Group. PFS forces a DH negoti-
	ation during Phase II of IKE-IPSec SA exchange. You can disable this or
	select a DH group 1, 2, or 5. PFS is a security principle that ensures
	that any single key being compromised will permit access to only data
	protected by that single key. In PFS, the key used to protect transmis-
	sion of data must not be used to derive any additional keys. If the key
	was derived from some other keying material, that material must not
	be used to derive any more keys.
PING	Packet INternet Groper. Utility program that uses an ICMP echo mes-
	sage and its reply to verify that one network node can reach another.
	Often used to verify that two hosts can communicate over a network.
PPP	Point-to-Point Protocol. Provides a method for transmitting datagrams
	over serial router-to-router or host-to-network connections using
	synchronous or asynchronous circuits.
Pre-Shared Key	The Pre-Shared Key is a parameter used for authenticating each side.
	The value can be an ASCII or Hex and a maximum of 64 characters.
Pre-Shared Key Type	The Pre-Shared Key Type classifies the Pre-Shared Key. SafeHarbour
	supports ASCII or HEX types
protocol	Formal set of rules and conventions that specify how information can
	be exchanged over a network.
PSTN	Public Switched Telephone Network.
-----R-----
repeater	Device that regenerates and propagates electrical signals between two
	network segments. Also known as a hub.
RFC	Request for Comment. Set of documents that specify the conventions
	and standards for TCP/IP networking.
RIP	Routing Information Protocol. Protocol responsible for distributing
	information about available routes and networks from one router to
	another.
RJ-45	Eight-pin connector used for 10BaseT (twisted pair Ethernet) net-
	works.
route	Path through a network from one node to another. A large internet-
	work can have several alternate routes from a source to a destination.
routing table	Table stored in a router or other networking device that records avail-
	able routes and distances for remote network destinations.
RTS	Request to Send. Circuit activated in hardware flow control when a
	computer (or other DTE) is ready to transmit data to a modem (or
	other DCE). See CTS, xon/xoff.
-----S-----
SA Encrypt Type	SA Encryption Type refers to the symmetric encryption type. This
	encryption algorithm will be used to encrypt each data packet. SA
	Encryption Type values supported include DES , 3DES	, CAST and Blow-
	fish .
SA Hash Type	SA Hash Type refers to the Authentication Hash algorithm used during
	SA negotiation. Values supported include MD5 SHA1	. N/A will display
	if NONE is chose for Auth Protocol.
