A breif overview of my home server lab topology.
1. Wireless Router (DHCP Enabled)
IP: 10.1.1.1/24
2. Server 2003 VPN Box (2 NIC’s)
NIC1 IP: 10.1.1.254/24 (Ethernet to router)
NIC2 IP: 10.1.2.253/24 (Ethernet to switch)
3. 5 Port switch conected to 3 other servers which belong to the 10.1.2.0/24 Network. Servers behind VPN include (DNS, DHCP, RADIUS, File, IIS, AD Cert, Exchange)
The VPN server is set as DMZ and has no issues with WAN connection with only NIC1 active. Once I promote RRAS (VPN + NAT) and/or Enable NIC2 I drop connection to outside world. When I set up RRAS I select NIC1 as connection for internet (This may be my problem).
My guess at how this works is NIC2 becomes router for the 10.1.2.0 network. I assume I need a default route for this network that points to NIC1. How does that route if NIC1 is on a different network? I also assume that the router 10.1.1.1 needs a static route inwards towards the 10.1.2.0 network. Am I even close? Can anyone throw me a few pointers? Any help is of course much appreciated 🙂
