Networking - How to...

Using SBS 2003, 2 NICs, Static IPs, Router setup. Configuration is:
(IP; SN; GW;DNS1)

INT NIC: 10.10.10.150; 255.255.255.0; empty; 10.10.10.150

EXT NIC: 192.168.50.100; 255.255.255.0; 192.168.50.254; 10.10.10.150

ROUTER IP: 192.168.50.254 configured with Static ISP settings.

WORKSTATIONS: 10.10.10.xxx; 255.255.255.0; 10.10.10.150; 10.10.10.150

Firewall Client is installed on the workstations.
Proxy server is enabled in Internet Explorer,although Internet works
without it enabled.

Situation:
We have added a wireless Access Point connected to the wired LAN for
(2) wireless devices. These wireless devices are both diagnostic
scanners for car repair and run Linux OS.

The wireless Access Point IP is: 192.168.50.244, with gateway of:
192.168.50.254(router)

Questions:

1.One of the wireless devices has an IP of: 192.168.50.117 and needs
to communicate with a software program installed on a workstation with
IP address of 10.10.10.106 on the wired LAN.
If we change the PC to 192.168.50.119;gateway: 192.168.50.254 and
disable the firewall client, the PC can connect to the Internet and
the wireless device. This wireless device does not have to connect to
the Internet as the software program on the PC provides this. This PC
runs Windows 2000 Pro SP4.

2. The other wireless device with IP of: 192.168.50.116 does not need
to communicate with the computer in Question1, but is needs to connect
to the Internet. With the setup above, this device works. However, if
we set it up like a workstation, it cannot connect to the Internet
even if we set the proxy server information in the device settings.

How can we setup these (2) wireless devices on our network as we would
a workstation? If the device in Question 2 would accept/work with the
10.10.10.xxx scheme, we would be fine.

Thanks!

It really depends on how your sbs server is configured. If it is
configured as a NAT router, the machines on the 192.168.50 network will not
be able to access machines on the inner 10.10.10 network. NAT is a one way
translation - you can get out from the private side but the machines on the
"public" side cannot see machines on the inside.

You should probably ask your question in the sbs newsgroup. Although it
is a routing question, sbs is a specialised product and is not configured
like other servers. You need specific sbs instructions to change the way
your sbs router/firewall works.
