Hi Arwin, the actual client Telnet App is a running in each domain. It looks for a way back to mainframe via a private IP connection over frame relay. Each domain has a connection to this FR cloud via a cisco 2500, howerver each workstation firsts hits another Cisco 1720 WAN router, looks at the header and determines which router to go out through. Our goal was to separate all financial data through the private FR segment and all other traffic goes through our own private VLan where at the one end we have our ISA server set up as a stand-alone connected to cable modem. All the routing on the isa box says here is a static route for all traffic back to their respective domains. While all financial data goes out only through the Cisco 2500. This has been working alright until 2 weeks ago when these telnet apps are starting to lockup for 5 minutes or so. I remove the firewall client and they no longer freeze. But interestly so, after removing the FC their email is still coming and going from an outside pop mail server.

Or does it get disconnected everytime you try to connect? Where is the host that you are trying to connect to located? Is it on the same segment? Have you allowed telnet protocol for atleast hosts PCs that you are using? regards, Arwin ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: pforster@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
