Hello!
I have this scenario on my small network with 10 PCs (connecting from outside to inside my network):
1) Modem with ADSL connection
2) Wireless Router with public IP on WAN interface
3) Switch
4) Server 2012 with DC/DHCP/DNS (with 2 NICs) and others servers/desktops machines
I want to share internet to servers and desktops.
I was able to share internet by 2 methods searching on google, but I am not satisfied with them:
First method - Using the Wireless Router and its DHCP Server
I turned on the DHCP inside the Wireless Router. All machines will get an IP and be able to go to Internet, but I don’t have the ability to control the DHCP and DNS in the router
how I would like to have, because the server DHCP and DNS must be turned off on Windows Server.
Second method - Using the Windows Server RRAS NAT, DHCP and DNS server
I have 2 NICs on the server:
NIC1 - CONNECTED TO SWITCH
IP: 192.168.1.1
MSK: 255.255.255.0
GTW:192.168.1.1
DNS:192.168.1.1
NIC2 - CONNECTED TO WIRELESS ROUTER
(the LAN IP of the wireless router is 172.16.0.1)
IP: 172.16.0.2
MSK: 255.255.0.0
GTW: 172.16.0.1
DNS: 172.16.0.1
After installing and setting the RRAS with NAT at the Server, the internet began to work on all machines but at some times the internet stop to load some random webpages, and if you hit a couple of times the F5 button, the webpage open sometimes, but very, very slow.
I saw other people in foruns saying that RRAS is not very good, and could cause weird things at internet connection, so, now I think the internet is horrible because of RRAS. After notice that internet is bad I tested it connecting a cable direct to the lan ports of the Wireless Router, and the internet works fast and perfect.
What is the best thing to do in my case to maintain Windows Server DHCP and DNS turned on and Internet be shared without loss of quality?
Thank you!
