• Jasomi Networks
  When a customer behind a firewall makes a call, the packets that reach the service provider's network are inconsistent and usually cannot be processed. The IP addresses and port numbers that were put in the packets by the user's phone became invalid as they traversed the user's firewall, due to network address translation. Worse still, NAT-firewalls adjust their NAT bindings frequently, and may arbitrarily close the pinholes that allow inbound packets to pass into the network they protect, eliminating the service provider's ability to send inbound calls to the customer. These problems are severe enough to have limited the deployment of IP telephpony services over leased lines or the Internet. VoIP presents several new challenges for firewalls, and it will likely be several years before they have the ability to deal with permanent pinholes NAT bindings, and the ability to distinguish a legitimate UDP packet stream originating at a service provider from an illegitimate denial of service attack originating elsewhere. The problems caused by NAT-enabled firewalls can be summarized as follows: the user's IP phone sends good packets to the service provider, but they are bad when they get there, they may be bad in different ways later on in a call, and, compounding this, the response packets from the service provider are denied access by the user's firewall because they look like attacks. Jasomi has created a new class of product that solves these NAT firewall problems without requiring any customer premise equipment. PeerPoint Centrex Edition resolves these difficulties by applying several translation techniques involving rules, state manipulations, and heuristics, as packets arrive and depart the service provider's premises. Situated near the edge of the service provider's network, PPCE accepts "bad" call signaling and media packets as they arrive from the user's IP phone. Then using Jasomi's VoIP translation engine, these "bad" packets are processed into perfectly well-formed, standards-compliant packets which are then sent from PPCE to the service provider's VoIP equipment. The service provider's equipment sees a properly formed VoIP signaling stream coming from PPCE rather than a non-conforming stream coming from the user's phone. Depending on the capabilities of the IP phone and the kind of firewall in use, PPCE may need to apply many different translations in order to ensure that the service provider only sees fully correct signaling streams. PPCE takes into account the firewall's NAT binding policy, packet admission policy, and pinhole time-out policy, as well as the presence or absence on the phone of supplementary NAT-traversal protocols which may themselves be standards-based (for example, STUN) or particular to the brand of phone in use. >>
