Ingate Launches Far-End NAT Traversal Solution

Remote SIP Connectivity Debuts with New Software Release

Stockholm, August 24, 2004 - For businesses looking to connect with home office workers and road warriors, Ingate® Systems (www.ingate.com), which produces and sells the world's only fully Session Initiation Protocol (SIP)-capable enterprise firewalls, offers Remote SIP Connectivity, an applications suite that enables far-flung users to leverage the benefits of SIP-based communications already integrated into the company's network.

Remote SIP Connectivity gives businesses a low-cost alternative to providing SIP-capabilities to all their employees. It is the only product available today that delivers far-end NAT traversal within the firewall itself, eliminating the need for costly session border controllers in the corporate environment.

Remote SIP Connectivity is being launched in conjunction with a new software release version 4.1.0 for all Ingate Firewall® and Ingate SIParator® products.

Ingate Remote SIP Connectivity

Ingate's award-winning products have long included support for near-end NAT traversal. When connecting users to a SIP-based VoIP network, NATs may be situated in remote locations not controlled by the enterprise trying to implement the communications service, effectively disrupting the VoIP connection. Far-end NAT traversal resolves this disruption by managing the traversal of the remote NAT from a central location. Remote SIP Connectivity allows displaced users to traverse a majority of NAT devices for simple call scenarios and connect with others on the global network.

Remote SIP Connectivity - which also includes a STUN server - provides one of the most comprehensive SIP-based remote connectivity offerings on the market. Ideal for situations where it is not practical or economically feasible to replace existing equipment with SIP-capable firewalls, Ingate Remote SIP Connectivity addresses a wide range of business needs:

• VoIP-enable single users working from home offices/telecommuters and even hotel rooms - without buying new equipment.
• For companies with staff who travel frequently, Ingate's solution lets employees traverse most basic hotel NATs so they can continue to use realtime communications while they're away.
• Revitalize Internet-based support services with the immediacy of "click to talk" features.

Ingate Secure and SIP-Enabled

Ingate's commitment to security is evident with Remote SIP Connectivity. All Ingate products support authentication and encrypted signalling. This prevents unauthorized contact, and does allow financial service organizations, ISPs and corporations to link with the remote site without risking eavesdropping. Inspection of the SIP signaling remains in place, preventing unwanted network intrusions.

Remote SIP Connectivity is available for all Ingate Firewalls and SIParators.

New Software Release Version 4.1.0

Ingate's new software boasts several new features, including:

• Support for authentication of SIP users from an external RADIUS server.
• More flexible NAT configurations, including the ability to choose which public IP addresses should be the sender when using NAT.
• VPN improvements including renegotiation of VPN tunnels and a VPN status page. Version 4.1.0 also allows for VPN between dynamic IP addresses.
• A DHCP server, assigning IP addresses to clients on the LAN.
• Support for multiple redundant DNS servers has also been incorporated.
• Improvements when handling certificates.
• The user interface has been enhanced, with particular emphasis on the SIP section.
• Improved logging of IP packets and IPsec negotiations.

Version 4.1.0 is free of charge for Ingate customers. To download 4.1.0, visit www.ingate.com/upgrades/.
