HI,
Welcome to SBS newsgroup.
Issue description:
===============
I understand that you want to set routing rules to rule the connection from
remote site to windows 2003 server on the main site.
Analyzing and suggestions:
===============
Before we go any further, can I assume that your network topology should be
following situation:
Internet ----[SBS]-[Internal client computer]
[remote client PC]--[router on remote site]---[Router on main
site]-[switch]---[Windows member server]
[UNIX server]
Then the SBS and Windows member server also connect to the switch.
Generally speaking, this should be the route issue. In order to narrow down
the issue, we need to gather the following information:
1. Please run ipconfig/all on SBS server Windows member server UNIX server
and remote site client computer, it is very important to our
troubleshooting steps.
2. Please also use route print on the problematic windows 2003 member
server and paste the results to the newsgroup.
3. Please use route add to add the 20.0.0.0 on the Windows 2003 member
server make sure that the metric is set to 1. You can follow the steps
below to add it.
Route add destination default gateway (should be the gateway on your main
site router) metric (should be set to 1)
Then test if the issue still exists or not?
4. If possible, please also try to change the default gateway on your
Windows 2003 member to point to the router internal interface then reboot
your Windows member server try to ping the router's internal interface on
the remote site to see what is the result? Please also paste the route
print on Windows 2003 member server also.
I really appreciate your understanding on this issue; please feel free to
post back your concerns. I am glad to be of further assistance.
Best regards,
Charles Yang (MSFT)

| Hi All.
|
| Long(ish) post here - so apologies.
|
| I have a client running the following kit;
|
| SBS2003 Premium SP1 server: 2 x NIC. 1st NIC = 10.0.0.4 / 2nd NIC =
| 192.168.1.10. 2nd NIC connected to Draytek router (IP = 192.168.1.1).
This
| connects to 2MB ASDL.
| Server 2003 member server = 10.0.0.5. This machine runs a SQL application.
| SCO Openserver 5.0.5 = 10.0.0.3. This machine runs a bespoke application.
|
| Everything is running nicely on the LAN, but we are having some problems
at
| a remote site. This remote site has 4 PCs. They are using 20.0.0.* IP
| config. They are all connected to a Draytek ADSL router (20.0.0.1) and at
| present use the windows vpn client to connect to the SBS machine. We've
just
| set up a PPTP passthrough on the router at head office. When more that
one
| person tries to connect from that site at any one time - the session
| crashes. This is a known problem with the Draytek - you cannot have more
| than one VPN connection from behind the same router.
|
| Anyway - they installed a new ADSL connection at head office purely for
VPN.
| I connected a new Draytek 2600 router and gave it an IP address of
| 10.0.0.240. This router is just connected to the network swtich so it
isn't
| going through ISA. I then set up Router - Router VPN from the remote
Draytek
| to the new Draytek at head office (the 10.0.0.240 one) which works fine.
| Now - the easiest box to test the connect is the Unix one. I created a
| static route from the Unix box to the remote network (route add 20.0.0.0
| 10.0.0.240). The remote site can communicate with the Unix box with no
| problems.
|
| My problem - I used the same route add command on the two Windows
servers,
| but the remote site cannot communicate with those boxes. Ping doesnt even
| work. I realise that command wont keep the route going after a reboot -
but
| that isn't the issue - the servers were never rebooted. Does anyone have
any
| suggestions, or am I barking up the wrong tree completely by trying this
| configuration?
|
| Thanks in advance.
|
| Robbie
