Implementation and Performance Study of a New NAT/Firewall Signaling Protocol
White Paper The NAT/Firewall NSIS Signaling Layer Protocol (NAT/Firewall NSLP) is a path-coupled signaling protocol for explicit Network Address Translator and firewall configuration within an extensible IP signaling framework currently being developed by the... [08 Jul 2008]
The Purpose of a SIP-Aware Firewall/ALG
White Paper Provided in this document is a brief description of the SIP and Network Address Translation (NAT) technologies. In addition, this paper will highlight problems that NAT causes for SIP, and how SIP firewalls/ALGs resolve the problem. [08 Jul 2008]
VPN and Firewall Traversal
White Paper Therefore there are problems when packet headers changes while in transmit across the network, by virtue of NAT devices such as firewalls. This paper present method proposed in IETF for making both initial IKE negotiations and subsequent... [30 Jun 2008]
Evaluating Application-Aware Firewall Performance
White Paper The rise of application-layer DoS attacks, the popularity of Network Address Translation (NAT), and the need for advanced network security capabilities have spawned the development of application-aware firewalls. [30 Jun 2008]
Path-Coupled Signaling for NAT/Firewall Traversal
White Paper This paper describes the requirements and design of an end-application triggered, path-coupled signaling protocol for NAT/Firewall traversal. Finally, the paper shows and discusses a performance evaluation, based on the implementation of the protocol. [31 May 2008]
Using JXTA for Firewall Traversal in Distributed CORBA Applications
White Paper JXTA is a peer-to-peer protocol stack, also implemented as free software, which can traverse firewalls and NAT gateways. JacORB is a free Java ORB that is ETF-compliant, that is, it supports the substitution of its transport layer in a standard way. [31 May 2008]
An Analysis of the Skype Peer-to-Peer Internet Telephony Protocol
White Paper This paper analyzes key Skype functions such as login, NAT and firewall traversal, call establishment, media transfer, codecs, and conferencing under three different network setups. Skype is a peer-to-peer VoIP client developed by KaZaa. [26 Apr 2008]
Solving the Firewall/NAT Traversal Issue of SIP: Who Should Control Your Security Infrastructure?
White Paper However, SIP-based communication does not reach users on the Local Area Network (LAN) behind firewalls and Network Address Translation (NAT) routers automatically. Firewalls are designed to prevent inbound unknown communications and NAT stops users... [11 Apr 2008]
NAT Traversal for VoIP and Internet Communications Using STUN, TURN and ICE
White Paper Increased penetration of broadband Internet is driving the adoption of Voice over Internet Protocol (VoIP) both for consumer and business markets, and VoIP is now on its way to becoming the main mode of multimedia communications in the coming years. [28 Feb 2008]
NUTSS: A SIP-Based Approach to UDP and TCP Network Connectivity
White Paper The communications establishment capability of the Session Initiation Protocol is being expanded by the IETF to include establishing network layer connectivity for UDP for a range of scenarios, including where hosts are behind NAT boxes, and host... [06 Nov 2007]
Windows Server 2003 Network Infrastructure
White Paper Topics covered in this session will include NAT (Network Address Translation) and ICS (Internet Connection Sharing), PKI (Public Key Infrastructure) and Certificate Services, Remote Access Policies, IPSEC (Internet Protocol Security) and IAS... [06 Aug 2007]
The Teredo Protocol: Tunneling Past Network Security and Other Security Implications
White Paper Teredo provides a way for nodes located behind an IPv4 NAT to connect to IPv6 nodes on the Internet. However, by tunneling IPv6 traffic over IPv4 UDP through the NAT and directly to the end node, Teredo raises some security concerns. [15 Dec 2006]
Bridging 802.11 Networks With Linksys
White Paper Typically, an access point acts as a central hub, router, bridge to Ethernet, and server for Dynamic Host Configuration Protocol (DHCP) and Network Address Translation (NAT), as well as other functions. [10 Nov 2006]
Teredo Overview
White Paper Teredo, also known as IPv4 network address translator (NAT) traversal for IPv6, is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 connectivity when IPv6/IPv4 hosts are located... [14 Mar 2005]
An Extension to the Session Initiation Protocol (SIP) for Symmetric Response Routing
White Paper This behavior is not desirable in many cases, most notably, when the client is behind a Network Address Translator (NAT). The Session Initiation Protocol (SIP) operates over UDP and TCP, among others. [26 Dec 2004]
