Old router died and just got the new one in and I can't figure out what I'm missing to forward dhcp and dns to windows server 2012.
Old router was a netgear R6300, new one is an N900. Before the router died the system worked fine, now that I'm trying to set up the new one all the wired computers are saying unidentified network and there is no connection.
The environment is setup as follows:
- The clients are wired to a switch, which is connected to the router.
- The DHCP/DNS server is plugged directly into the router
Troubleshooting I've done:
- There are wireless clients also, and they can access the internet fine.
- Right now the wired clients are not receiving IP addresses.
- Bypassing the switch and connecting a client directly to the router does not solve the problem.
I've setup the router as follows:
- port forward 53 to server
- uncheck use router as DHCP server
- We have a static IP from our provider and I put that in.
- Under DNS Address in router I put the ones provided from our ISP (If I put the server IP here the system goes down)
- I checked the predefined options in the DHCP and I can see the router is in there correctly
- I checked the DNS and saw that I have the correct settings for the DNS servers
So what am I missing? do I need to add a static route? forward DHCP? I feel like I'm overlooking something simple, and all I did was replace a broken router, so any tips would be greatly appreciated.
