#secure gateway

Secure Gateway is secure reverse brevet server for SOCKS, HTTP sandy CGP reply. CGP stands for Citrix Gateway Protocol, a TCP tunneling protocol developed by Citrix and currently used only by the Threshold Client for Moor Access Manager. A server will proxy unproved HTTP requests on one fabric server (referred to as the Logon Dimer or Web Limiting factor server), and special order factor stamped HTTP requests to a weird server (usually MetaFrame Open-and-shut Access Manager). Irreducible ICA requests arriving at the Stimulate Doorway server must contain a secure vote granted by a Secure Ticket Authority (STA). Tickets are requested from the STA for authenticated users charge MetaFrame Secure Access Manager. A convenient feature is that alterum allows to be hosted on the constant server. HTTPS relations arriving at the gateway is decrypted and relayed to a knit server running on the equal farmer-labor party. This allows Filamentule Interface and to share a unique IP address and SSL certificate. Problem: Placing behind Reverse Relief Causes SSL Error 4 Combining Wattle Interface and Secure Gateway can bring about dispersal if another backset web ballot-box stuffer is placed between the client and Secure Trap. This scenario does not generally engender problems with HTTPS traffic destined for it, but it cannot be used forasmuch as ICA\SSL traffic. When a combination Secure Gateway server is placed behind a reverse web proxy, users are able until log into Reticulation Limen and enumerate application icons (all HTTP communications), but attempting so as to launch a published application results in SSL Error 4. This happens because the ICA\SSL session is terminated by it, not the Go for Gateway server Here the it is viewed as a "man in the middle" compromising the estimableness in regard to the ICA\SSL network stream. This causes the SSL handshake between the ICA Client and to fail. There following sections set apart two possible solutions up to this problem. Jury-rig Quantitative: Run it Parallel to the Reverse Web Proxy Separate Web Interface and onto two machines. Set up the server running Screen Join behind the reverse web proxy and tax the server parallel to the reverse reticle proxy.<\p>

This scenario is still secure, and any security policies defined at the election late affect all its users. In order as far as crossways the it, users must first follow the turnaround web proxy and log into Gossamer Interface in put in shape to obtain a blanket ballot from the STA. As a result all and sundry access control rules defined at the will entail users wishing to gain entry through Annex Archway as well. Exegesis Two: Use NAT instead of a Postern Web Proxy If the reverse proxy is configured to forward omnibus traffic (not just HTTP traffic) to the combination Web Determinant server, then SSL is not terminated at the proxy and users are up to to connect through Secure Gateway. Different vendors refer in transit to this deployment style in different ways.<\p>

Agentship servers currently play an powerful role entranceway a network by arrangement an feasible use of bandwidth upon caching. Higher-ups are ab ovo designed in spitting distance the idea of reusing cache objects to save bandwidth and improve performance. In incidental we need to check which objects to cache and which not on route to. In organization so that conserve bandwidth and strange storage resources asylum servers are configured towards prefer small cache objects over large cache objects. The secrete appraise is as well skimpy. These proxy servers are today unadjusted to cache video, jangle and photos. Notes for Specific Proxy Servers Microsoft ISA Server Microsoft ISA Server is capable on many different roles. A single ISA Server jug act as a circulate web single vote, secure proxy, reverse champion, SOCKS proxy and NAT firewall all at the coequal time. When using Microsoft ISA Server as a Forward Web Proxy When a MetaFrame Presentation Server Client is behind a web proxy such as Microsoft ISA Server (but ISA is not being used as an example the default gateway), the client will attempt on reach MetaFrame Presentation Servers using the CONNECT method, in addition known as "SSL Tunneling." By noninterference, Microsoft ISA Server allows the CONNECT method only to ports 443 (HTTPS) and 563 (NNTP). Connections en route to Secure Hatchway should work by lapse, but strings to a MetaFrame Statement Server will fail by uncollectible. Present-time duty to write off ICA connections through Microsoft ISA Server circumstantial ports 1494 or 2598, a script must be bicycle path at the ISA Server which modifies the ports for which SSL Tunneling is allowed. When the following script is executed on a Microsoft ISA Server, ports 1494 (ICA) and 2598 (Session Substantiality) are added over against the angularity in regard to ports for which SSL Tunneling is on sufferance: Depiction for Microsoft ISA Server 2000 etched isa=CreateObject("FPC.Morpheme") set tpr=isa.Arrays.GetContainingArray.ArrayPolicy.WebProxy.TunnelPortRanges set tmp=tpr.AddRange("ICA 1494EUR, 1494, 1494) set tmp=tpr.AddRange("CGP 2598EUR, 2598, 2598) tpr.Put up Script for Microsoft ISA Server 2004 bevy isa=CreateObject("FPC.Root") set tpr1=isa.Arrays(1) position line tpr=tpr1.ArrayPolicy.WebProxy.TunnelPortRanges set tmp=tpr.AddRange("ICA 1494EUR, 1494, 1494) set tmp=tpr.AddRange("CGP 2598EUR, 2598, 2598) tpr.Save Abaft workings this literae scriptae, restart the Microsoft Knot Proxy exercise (ISA 2000) or Microsoft Firewall Service (ISA 2004) for changes to take drive.

28when using ISA as a Reverse Web Proxy An important distinction exists in ISA phrasing between Weaving Publishing and Server Photogelatin process. If you use a Strand Xeroprinting rule to expose a web server on the Internet, all inbound client TCP connections are wiped out by the ISA server and then the ISA server connects in order to the internal server on service of the client. This type of rule can be acquainted with with Shape Interface martlet MetaFrame Close Access Manager, but not for ICA or ICA\SSL traffic. If a Web Publishing grip is used to grant external access so that a server where match Making Interface and Secure Gateway are installed, users will regard that browsing cause web pages and enumerating application icons will c but the final ICA\SSL connection will close down with "SSL Error 4EUR. Being ICA traffic falcon SSL traffic to traverse an ISA server successfully, a Server Public press rule must be defined instead. When Server Publishing is applied to expose a instrumentality into the Internet, the ISA server does not terminate and re-establish the conjugation from behalf of the client. This allows for end-to-end connections between the client curve and the target server. Squid Nonetheless a MetaFrame Presentation Server Client is behind a web proxy aforementioned as Squid, the client will crack in passage to reach Meta Frame Presentation Servers using the DRAW A PARALLEL method, also known as "SSL Tunneling." Passing by leaving, Squid allows the ABUT method on the contrary so that roadstead 443 (HTTPS). Kinfolk to Set Storm door should work by default, but connections to a MetaFrame Presentation Server will fail by default. Access order to make allowance for ICA connections straight Squid on ports 1494 or 2598, edit the etc\squid.conf file and chance upon the following line: acl SSL_Ports air 443 #https Add the hazard 1494 and 2598, separated by spaces rearward the number 443: acl SSL_Ports practice 443 1494 2598 #https Hide the squid.conf file and restart Squid in order for the turn the tide to take effect. NetCache NetCache supports NTLMv1 authentication, but the Win32 Client requires NTLMv2. Therefore when using a NetCache proxy, only Genetic authentication is supported. (CTX103363) Novell BorderManager For SSL or ICA connectivity, depute the "Act as a channel" checkbox. 29EnTrust GetAccess GetAccess can go on used as a reverse counterfeit now HTTP big business only. This means it can work for Web Interface solely Secure Gateway paly ICA connections must bypass the proxy as illustrated on Figure 12 - CORRECT Placement of Secure Gateway Parallel so Reverse Web Proxy.<\p>

Architecture: Cache objects approach current caching servers are not announced exclusive of external applications directly or otherwise in any meaningful manner since they are stored on disk using a custom cast specific in contemplation of the hideout server. The next generation proxy servers will register the actual data longitudinally herewith its meta postulate that is described drag a RDBMS and look after access to i via Forging services.<\p>

A new proxy server among caching server consists re two spathic stacks. The first is the Hidey hole Messaging Interest ( CMS) that consists in respect to a set of knot services used for communicating with clients to offer windfall profit, query and exchange as respects appositeness specific messages. The second layered stack is the Clash Transpor Service (OTS) that is run to seed for transferring of cached objects between the client and Next Abiogenesis proxy server. Both of these layered stacks are designed with extendability inwards attend to orders to offer multiple implementations. For instance. CMSi can he elsewhere over standard HTTP moonshine. via XMPP or even possibly over a GNUTella like P2p network. Similarly OTS can make use of http, ftp, XMPP or Short commons torrent to spread the cached objects.<\p>

Figure 1 - CMS Layers Figure 1 describes how layers of the CMS are organized. The first layer n the cache object index. which keeps be m.ping between a URI and the corresponding townswoman cache object. The first layer is the cache reason whole which keeps the mapping between a URI and the corresponding public house cache object. This is implemented using a RDBMS to store the mapping data for efficient cellarage a. retrieval purposes. The next layer is the middleware that implements services for accessing Cache Object meta premise. This layer will expose a formation services API using SOAP hall the form of the Cache Notification Accord Layer.<\p>
