Hi AT
I am trying to set up a file server/router box to replace my wireless router. Ignore the wireless part for now, I'll deal with adding an AP later. Essentially, I have a little always-on file server:
FD Node 304 m-ITX case w/ CoolerMaster Silent Pro 450w (41 dollars for an 80plus gold PSU, hoorah!)
Gigabyte H77n-WIFI for the mobo (mITX with dual gigabit lan? Chea)
i5-2500k (not an ideal choice but I already had it laying around)
This is running Server 2012 R2 DC (because why not?) preview
The idea is that it will sit between my modem (Thomson DCM 475) and my switch (which is in fact a Cisco RV220w, only I'm not using the WAN port. I also disabled its' DHCP server and DNS proxy functions). It will be configured as an ActiveDirectory Primary DC, so running DHCP + DNS + AD-DS + RRAS (Directaccess, VPN, routing)
The problem I have been encountering is really basic. When I plug the modem directly into one of the NICs on the file server's motherboard, I can't get a connection to the internet. Modem works fine when plugged into my router, has worked fine in the past directly plugged into my laptop or desktop.
It has an IP address of 192.168.100.1
It assigns an IP address to my server of 169.254.xx.xx
When I manually assign my server's NIC an IP of 192.168.100.x + Subnet 255.255.0.0 + Def Gateway 192.168.100.1, and since it requires DNS I use google's public DNS (8.8.8.8, 8.8.4.4).
Everything seems to work correctly with those settings, except it won't resolve DNS!
Have tried factory resetting the modem to clear its DHCP tables etc, nothing seems to work. I can even connect to the modem's diagnostic page, still no DNS resolution
Anybody see what I am doing wrong?
