Server 08R2 Front End networking probs

korsen · 02-27-2010, 09:08 PM

ok so what i'm trying to accomplish is getting my server to be a front end for my network. i'm doing all this to learn from experience so I don't know alot of things.

Modem -> Server / Server -> Netgear WGR614v9 -> Rest of network

I already have AD DS, DNS, and DHCP roles installed. DHCP is green, I guessed on DNS and the forward lookup zone has both NIC IP's in there under Host(A) on (same as parent folder) which there is none, and my Nic->Netgear address on Tower(comp name). Reverse lookup zone has Nic->Netgear address. My netgear has obtain DHCP/DNS automatically (which shows it's receiving the IP's I set) and my NIC->Modem is automatically obtained until I can set my ISP service to DDNS. My NIC->Netgear IP is 192.168.1.100, 255.255.255.0, 192.168.1.1 with 1.100 as DNS server (i'm guessing the gateway is wrong but i'm not sure what to put).

I'm eventually going to install Exchange server, and ISA server so keep that in mind.

From Netgear->Network I can ping the network computer, the netgear, and the nic supporting the netgear. Apparently the DNS works slightly because pinging google finds it's IP address but doesn't connect to it. From the Server I CANNOT ping the router. It has an option to respond to internet ping requests which is off, but I have not tested pinging the netgear with that option on.

I'm basically entirely confused at this point. I want the server basically to filter traffic and scan for viruses etc. It's a powerful rig so there shouldn't be any problems overloading it.

Hopefully your help will be enough.
Cheers.

So basically your server machine is acting as the router, since it connects to the modem. The netgear is an access point and switch.

First - have you made sure you turned off DHCP on the netgear, and are NOT using the "Internet" port at all?

Do you have RRAS (Routing and Remote Access) installed on the server? You didn't mention it and your server will not route network traffic to the internet without it.

Yes I installed RRAS, sorry forgot to mention it. The netgear HAD DHCP turned on - I don't understand how my server can provide IP's through the netgear but you guys are the pro's, so it's off now. (I know it's possible I just can't connect the dots in my head)

I also read in another thread the server should connect to a regular 1-4 port on the router, it WAS in the internet port. So as of this moment, the OP still stands plus the changes suggested in your post.

Thanks for the help.

They werent before, but they are now. Btw, this might be what's supposed to happen but when the router is connected to my server I can't acess it's config page without removing the server connection.

So as it stands, everything is still as stated in the OP plus your suggestions.

Thanks for the help

No edit? Sorry, wanted to make sure we're still clear that my network is still in bad shape

Also, only because I can't find an answer for this anywhere, under DHCP - IPv4 and my Scope has a white ! inside a blue circle and I don't know what it's for.

scratch that. found out i had a DNS server IP on my NIC->Netgear that can only be reached by my NIC->Modem connection. After I removed those servers it went back to a green check mark.

And if anyone could direct me to the nearest edit button i'm sure we would both appreciate it
