Site to Site VPN sbs 2003 ISA 2004 w/ hardware devices



Hello,

I'm attempting to setup site to site VPN between office A with SBS2k3
premium Sp1 w/ ISA 2004 and office B with a 3rd party hardware gateway
device. I have two hardware devices that I'm trying: a Dlink DFL-200
or a Zyxell Zywall 2 - both with advertised site to site vpn ability.
Attached is a document containing ipconfig's and ip settings.

My issue: After configuring ISA2004 and the hardware devices, I cannot
ping either direction - however I've checked and double checked
settings. ISA2004 does not report any issues - all seems setup there -
network rules, access policies checked and double checked. Any ideas
of what the problem may be? My sbs has the traditional 2-nic setup.
My ipconfig's follow this message.

I'm following as my guide the many fine seeming resources on
Microsoft's site as well as a few others for comparison.
http://support.microsoft.com/?id=888711 - site to site VPN w/ ISA 2004
from MS
http://www.isaserver.org/articles/2004isadlink.html - ISA 2004 to dlink
hardware device article
http://www.microsoft.com/technet/prodtechnol/isa/2004/plan/sitetositeipsec.mspx
- configuring ISA 2004 and 3rd party gateways.

I've also read other articles - Microsoft has some device specific
articles - none of which are for my devices, but enough to believe that
my devices are probably configured correctly.

Is there anything I need to configure within SBS I wonder? Eventually
I would like to have a replica domain controller at site B - but
obviously a working VPN comes first.... Please help!

Thanks,

David Fields
