Please describe your ISA configuration in better detail: Q1 - how many interfaces on the ISA Q2 - how many network objects are defined? -----Original Message----- From: alexl@xxxxxxxxxxxxxxxxxxx [mailto:alexl@xxxxxxxxxxxxxxxxxxx] Sent: Thursday, February 03, 2005 7:41 PM To: [ISAserver.org Discussion List] Subject: [isalist] VPN to defined network http://www.ISAserver.org It seems that if vpn client comes from default External network, everything works fine on ISA2004. When I define an external network X with some specific address subset, firewall denies connection to port 1723 (pptp) even if I make sure that network X is checked on the list of allowed source networks. If vpn clined is coming from X it gets denied right from connection to local host port 1723. As soon as I remove this specific network and client becomes part of default External network, VPN connection works like a champ. Any ideas, please, I am at the end of the rope here. ------------------------------------------------------ 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 ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx All mail to and from this domain is GFI-scanned.
