Hi all,
Hopefully not too strange a query here.
We have a nice working SBS2000 set-up here, Internet connection via 2nd NIC
and Broadband Router. We also have a PBX which also acts as a Router and
also provides some nice CTI functionality. Query is this:
We [or more specifically certain users on the LAN] need to be able to route
out via the PBX's integral router to certain customer sites. To access the
full CTI functionality of the PBX we need the PBX sitting on our INTERNAL
LAN range. By default obviously, any packets not destined for the internal
LAN get routed outwards by the Server - hence no routing to clients via the
PBX...
What I've done thus far is this:
1] Moved the PBX to our internal LAN [was previously sitting between the
external NIC and the Broadband Router - worked fine in that set-up but less
CTI functionality] and assigned it a fixed IP address on our LAN which is
reserved in the DHCP set-up on the SBS box. In the Router config on the PBX
I've entered a default route pointing at the Server's internal NIC address
so that any packets not for any of the PBX defined routes/addresses get
passed to the SBS box.
2] This has enabled the full CTI side - so far, so good
3] Re-ran the ICW and Internet access is working fine from both Server and
LAN clients
4] I've also amended the DHCP scope to have the PBX/Router as another Router
and moved this to be first in the list of router addresses provided via DHCP
5] From a standalone laptop without the ISA client, I can route to clients
via the PBX no problem - so it *appears* that the DHCP/routing side is
working fine
6] From LAN clients we *can* now ping remote clients using the PBX router,
whilst still having full Internet access via ISA and our broadband
connection
7] However, from my PC with the ISA client I cannot route via the PBX using
the PBX management software
8] If I connect a standalone laptop to our LAN side as a DHCP client, I
*can* use the PBX management software and route via the PBX router - only
change is that it does not have the ISA firewall client installed
I *think* that the ISA client *appears* to be the likely thing I need to
configure somehow but I'm unsure how to do so - can anyone provide any
pointers?
What I want [ideally] is to have all packets from any LAN clients going to
the PBX/Router initially and if they're destined for one of the remote
clients on that side, get routed by the PBX. If not, the packets should be
forwarded to the SBS box and dealt with as normal.
Or is what we're trying to achieve impossible?
Thanks in advance,
David
