that augments a firewall or NAT employed in a computer network. It allows customized NAT traversal filters to be plugged into the gateway to support address and port translation for certain application layer application layer gateway sip on or off "control/data" protocols such as FTP, BitTorrent, SIP, RTSP, file transfer in IM applications, application layer gateway service windows 7 etc. In order for these protocols to work through NAT or a firewall, either the application has to know about application layer gateway settings arris an address/port number combination that allows incoming packets, or the NAT has to monitor the control traffic and open up port mappings (firewall pinhole) dynamically as required. Legitimate application data can thus http://computerstepbystep.com/application_layer_gateway_service.html be passed through the security checks of the firewall or NAT that would have otherwise restricted the traffic for not meeting its limited filter criteria. Contents 1 Functions 2 ALG service in Microsoft Windows 3 See also 4 References 5 External links Functions[edit] An ALG may offer the following functions: allowing client applications to use dynamic ephemeral TCP/ UDP ports to communicate with the known https://en.wikipedia.org/wiki/Application-level_gateway ports used by the server applications, even though a firewall configuration may allow only a limited number of known ports. In the absence of an ALG, either the ports would get blocked or the network administrator would need to explicitly open up a large number of ports in the firewall — rendering the network vulnerable to attacks on those ports. converting the network layer address information found inside an application payload between the addresses acceptable by the hosts on either side of the firewall/NAT. This aspect introduces the term 'gateway' for an ALG. recognizing application-specific commands and offering granular security controls over them synchronizing between multiple streams/sessions of data between two hosts exchanging data. For example, an FTP application may use separate connections for passing control commands and for exchanging data between the client and a remote server. During large file transfers, the control connection may remain idle. An ALG can prevent the control connection getting timed out by network devices before the lengthy file transfer completes.[2] Deep packet inspection of all the packets handled by ALGs over a given network makes this functionality possible. An ALG understands the protocol used by the spec

Its all related to networking... Click here for some info about it. BTW when exactly does this msg come up? What OS are you using? pvc9, Aug 31, 2002 #2 RonK Thread Starter Joined: Apr 29, 2000 Messages: 853 Thanks application layer gateway for the quick reply ! The message comes up only while on the internet and I am using XP Proffessional. RonK, Aug 31, 2002 #3 pvc9 Joined: Jul 7, 2002 Messages: 6,427 If its not causing any problems then its Ok. But I can understand that it might be to see the error come up all the time. All I can suggest is contact your ISP and may be he can do something. But you could wait if you want to to see if any other members have some useful suggestions. pvc9, Aug 31, 2002 #4 RonK Thread Starter Joined: Apr 29, 2000 Messages: 853 OK - Thanks RonK, Aug 31, 2002 #5 Sponsor This thread has been Locked and is not open to further replies.
