Site to Site IPsec VPN between ISA 2004 and Netgear FVS318

Last Modified: 2012-05-05
I currently have two ISA Server 2004 systems setup that I am trying to establish Site to site vpn connections with a Netgear FVS316 VPN router.  I am able to establish the connections but and I believe that the comminication is only one-way.  When I am connected to a machine that is behind the Netgear, I can ping any system that is behind either of the two ISA servers.  I can also ping any system that is behind the netgear from any machine that is behind either of the two ISA servers.  What I cannot do is ping any system behind the netgear if I am actually on either of the two ISA servers.  I believe that this a configuration issue within my ISA servers.  My Netgear indicates, in the VPN status dialog, that both of my connections are established.  So my question is, why can I not ping the Netgear or any machine that is behind it, when I am actually on either of the two ISA servers?  It would seem to me that if I can ping the systems on the Netgear from any machine that is behind the ISA servers that I should be able to ping directly from the ISA server itself.

Any help is appreciated!

I am assuming you mean a firewall policy for the VPN connection that has localhost listed in the From dialog.  It is configured this way currently!
On your isa server run a log where client ip = <ISA SERVER IP ADDRESS> and see what happens when you ping.  See if you get "DENIED - DEFAULT RULE" or what happens...


I ran a trace on the ISA server but could not get anything to come back.  One thing that I did notice was that when I tried to ping the Netgear box from the ISA server, it came back with "Negotiating IP Security" as opposed to "Response Timeout".  Not quite sure what this means.
