Hey guys, I have the following scenario at work:
- We have a Windows 2008 domain, on 192.168.11.x, using DHCP
- The Department of Finance has given access to their system, so our finance office can work in their database, though the browser. We have no control over their end of the connection, just the access info they gave us.
Their web based software is located at address 10.1.1.100, to which we have a straight DSL connection, DSL modem ip 10.3.7.x /24
Connecting a pc to the DSL modem, giving it a static IP in the same range, gives us access to the site at 10.1.1.100. So far so good.
However, we need a total of 5-10 computers connected to this system.
First (and quickest) option was to add a second NIC to the PC, which is connected to our network, and then give the assigned users access with RDP. This also worked, up to the point that more users had to be able to work on the system at the same time. Conclusion: RDP is not a viable long term solution.
We decided to add a router. The router is given a WAN address of 10.3.7.x/24 and a LAN IP 192.168.222.x/24, no DHCP. We then added a static route in the router to 10.1.1.100/24.
Connecting a PC to the router, with static IP 192.168.222.x/24, we are able to access 10.1.1.100 through the browser. Works, for multiple machines!
However, the idea is that assigned users should normally work on our domain, and ALSO have access to the finance system at 10.1.1.100. Adding a second NIC in their machines should have helped with this.
NIC1: 192.168.11.x (via domain DHCP), GW: Domain gw
NIC2: 192.168.222.x (Static), no gw
As soon as both are connected, there is no access to the finance system. Unplug the cable from NIC1, and it works fine.
We tried changing the metric, to no avail.
This is one of those "It's probably right in front of me, but I can't see it" moment, so we turn to the masters and gurus in this community with a humble request for help.
