I am having trouble setting up two networks.
Basically, i want one 'private' network and one public network.
The problem is, the private network can't access the internet.(Network 2)
Network 1(Public) works fine as i don't want them to access Network 2.
Here's how it is setup.
Internet
|
Router/Modem (Network 1)
|
Server NIC1
Server NIC2
|
Switch - (Network 2)

Network 1 can access the internet and shared files on the server.
Network 2 can access Shared files on the server (which is what i want) but cannot access the internet.
If it helps, router/modem IP is 10.10.1.254 subnet 255.255.255.0
Server NIC 1 IP is 10.10.1.252 subnet 255.255.255.0
Server NIC 2 IP is 10.10.1.251 subnet 255.255.255.0
How can i get computers in Network 2 to access internet?
Thanks in advance.

Re: Multiple NIC's - Two Networks

Hi,

What is the default gateway set to on the clients in network 2?

Re: Multiple NIC's - Two Networks

Daolsky according to your ip addressing you do not have two networks. All you have accomplished is to put two nics in the same network.

google installing RRAS

Nic 2 needs to be in a different ip subnet. The rras doc will walk you thru it.

Hi,

What is the default gateway set to on the clients in network 2?

Their default gateways are showing 10.10.1.251

Re: Multiple NIC's - Two Networks

Thats alright. You need to do what Wanderer has suggested and put NIC 2 on a different subnet.

Re: Multiple NIC's - Two Networks

Thanks for your help. Have been extremely busy. Will try that solution over the next day or so. Will let you know how it turns out.

Re: Multiple NIC's - Two Networks

Sorry for the MAJOR delay in replying. I was unable to resolve the issue.
I have since changed some of my equipment and have decided to give it another go.
Here is my current setup

Internet
|
Modem/Router(192.168.1.254)(network 1)
|
NIC1 (IP 192.168.1.1, subnet 255.0.0.0, gateway 192.168.1.254, dns1 127.0.0.1, dns2 192.168.1.254
|
NIC2 (IP 10.1.1.100, subnet 255.255.0.0, gateway (blank), dns1 127.0.0.1 dns2 (blank)
|
SWITCH(NETWORK2) (Clients are assigned ip range 10.1.1.1 - 10.1.1.99) on subnet 255.255.0.0, gateway empty, dns servers are 10.1.1.100, 192.168.1.254, 192.168.1.1

Network 2 is still unable to access internet. i can ping others in same network, and the server on NIC2 but nothing on network 1 or internet.

I made sure they were on different subnets this time.:facepalm:

Thanks, D

Re: Multiple NIC's - Two Networks

Did you engage RRAS?

Re: Multiple NIC's - Two Networks

I have just installed the Remote Access Role (Server 2012). Ill give it another go this afternoon.

Thnks, D:banghead:

Re: Multiple NIC's - Two Networks

I have installed Routing and remote access though I am a little unsure of how to configure it. I don't really have any need for remote access from outside, other than RDC so I am assuming I want NAT?

My NIC1 card is assigned my public IP address if that makes a difference.

 

[Wand3r3r]

Re: Multiple NIC's - Two Networks

Nat is the correct course of action.
I would say you are almost there with your configuration.

 

[Daolsky]

Re: Multiple NIC's - Two Networks

I have installed NAT. Network 2 is on a different subnet to Network 1, has a different IP range, but what about DNS? Network 2 has no trouble obtaining IP, subnet etc, but internet is still not working. I have tried specifying a gateway as well as leaving it blank. The DNS servers specified are my server (10.1.1.100), the modem's internal address (192.168.1.254), the modem's external public IP (xxx.xx.xx.xx), as well as google's public DNS 8.8.8.8 and 8.8.4.4

I appreciate the help

Also what do i need to do to make sure NAT is configured correctly

Re: Multiple NIC's - Two Networks

lets see a ipconfig /all from the server

Might want to read up on DNS and how to properly configure it. Might want to google TechNet and dns.

"The DNS servers specified are my server (10.1.1.100),[correct] the modem's internal address (192.168.1.254) [incorrect], the modem's external public IP (xxx.xx.xx.xx),[even more incorrect] as well as google's public DNS 8.8.8.8 and 8.8.4.4 [no point in these for the lan]

Here is the ipconfig /all.

Am looking into the DNS

 

[Wand3r3r]

Re: Multiple NIC's - Two Networks

OK that ipconfig looks good.

In the servers dns server you need to put the isps dns ips in the forwarders [not to be confused with forward lookup zone]

Then from a workstation do a nslookup your domain name and then do a nslookup server name. Post the results for review

 

[Daolsky]

Re: Multiple NIC's - Two Networks

Here are the results from the nslookup.

I also did a lookup on mydomain.co.nz and it shows my old public IP address (I have yet to contact the domains registrar to update it)

 

[Wand3r3r]

Re: Multiple NIC's - Two Networks

Looks good. From a workstation do a nslookup yahoo.com and post the results for review.

Next do a tracert yahoo.com from a workstation and post those results also. Thx

 

[Daolsky]

Re: Multiple NIC's - Two Networks

I have done the nslookup and tracert.
Nslookup seems to work, but tracert does not.
DNS still not correct?

I really appreciate all the help.

Re: Multiple NIC's - Two Networks

Ok after my last post, i thought i'd try checking routing, and found my NAT was not configured correctly. :facepalm:


Of all the things to miss I missed the checkbox saying "Enable NAT on this Interface" (as you can see in the picture attached.)

Thank you for all your help. (Can't believe I missed that!)
