We just covered this in another thread. If the internal hosts don't have a local route to the remote WAN subnet, they can't get there. All internal hosts MUST be SecureNET in order to cross into the WAN. -----Original Message----- From: Wayne Berry [mailto:wayne@xxxxxxxxxx] Sent: Thursday, February 10, 2005 10:56 AM To: [ISAserver.org Discussion List] Subject: [isalist] FW: Split Routing? http://www.ISAserver.org ISAList: In my office I would like to put up a ISA Server 2004 as a firewall for outside access, and as a Site-To-Site VPN. Traffic that is going for the outside work (isaserver.org) would just go out my External network. Traffic going for our RACK in co-location would be tunneled out the VPN (over the External network) and decrypted by the PIX that we have at collocation. 1) I have the Internal To External Working 2) I believe the VPN tunnel is up (we had a SOHO To PIX working previously so I know the PIX is set up right), however how do you check the VPN tunnel on the ISA Server 2004 is up? Is the only way to know to send traffic over it? i.e. ping, tracert, etc... 3) I have the a Network Rule that Routes Traffic Between Internal and Co-location (FiberCloud) http://www.xcache.com/images/xpisa/NetworkRulesScreenShot.bmp 4) I have two Firewall Polices for All Traffic between my office (Crown Plaza) To Co-Location (Fibercloud) and Back: Http://www.xcache.com/images/xpisa/FirewallPolicyScreenShot.bmp 5) But From the Internal network I can't ping, trace route, or connect to IPs that I have defined as being part of the VPN network. So either the VPN is not established, which I don't know how to test, or my routing rule isn't working or my policies are preventing my from getting there. Does anyone have a couple of quick tests that I can use to figure out what the issue is. BTW I read: Creating IPSec Tunnel Mode Site to Site VPNs with ISA Server 2004 Firewalls http://www.isaserver.org/tutorials/2004ipsectunnelmode.html To get this far, however none of them deal with split traffic, where some traffic is headed external and some is headed to the VPN. -Wayne The ISAPI Dev pretending to be an ISA Admin for the day ------------------------------------------------------ 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.
