Hi,
You can also monitor your RRAS by using the following from MS:

You say you "have routing enabled" on the ISA.
Does this mean that the RRAS server is the ISA default gateway, or have
you just enabled IP routing in ISA? ISA must use the RRAS box as the
default gateway to the Internet if it's to route properly. Your ISA
ISAInfo (http://isatools.org/isainfo.1.9.5.zip) and the RRAS box
ipconfig/all output will be very useful.

Hi All,
I have a specific requirement and would like to know if this is
practically possible and if so some guide lines.
I have deployed an ISA box with a lot of help from the Guides and
Articles posted here.All my internal network exists behind this box. Now
i have two Internet Service Providers. I also have a remote site to
which i require VPN connectivity. This is configured using a windows
2000 server and placed out side the ISA box. This box, which i will call
the VPN box, has multiple NIC cards. One of the NIC's is used for local
lan, one each for my two ISP's. My ISA box also has Routing enabled to
direct all requests to my VPN box.
My requirement is to be able to provide routing functionality on this
server, such that i can selectively pass traffic through my ISP's. This
i am able to do well enough on the VPN box. But my clients having a
gateway to my ISA box, are in no position to take advantage of this
routing. For eg: If i do a tracert for http://www.hotmail.com/ from my
VPN box, it does find the target. But when i do the same from one of my
client machines behind the ISA, it finds till the VPN box and then drops
all packets destined to the internet. But the packets to my remote
network get routed to the VPN correctly.
Thanx in advance.
