VPN Server behind firewall on single NIC
Posted on 2007-10-18
Customer is running small domain on win2k server sp4. There is a ADSL modem/firewall/router providing internet access. Customer wants VPN operational. I haven't played with VPN on windows server & have been reading up on this. Customer is not interested in buying another server for VPN so it's got to be on the DC & I'm interested in minimal disruption & reconfiguration in the network. So my question boils down to this:
Is it possible to implement VPN using only the current single internal NIC on the server?
I can configure whatever is required for routing/port passthru/etc so this is not an issue.
I did start just trying to test it but of course as soon as I installed/enable RRAS it blocked the LAN & I had to stop the server to allow LAN access.
Please note that whilst I mark my level on this as beginner, that is to do with my VPN knowledge only.
