I have a fairly simple problem, but I just can't seem to find a good tutorial or anything that simply explains the steps I need to do to solve my problem. I have server 2008 Ent. installed on an old Dell Inspiron 530. I installed a second NIC to serve as my gateway. I have Active Directory, DHCP, and DNS services installed. I have a static IP which I bought from my ISP, and assigned it to my 1st NIC - External. The 2nd NIC - Internal; will be used to spit out private addresses of 10.x.x.x. The DHCP server is working as far as I can tell, because all other PC's are receiving 10.x.x.x addresses. I tried to setup NAT using the wizard, and I went into DNS, and set the forwarders to my ISP's DNS settings; but I am still not able to get online on my other PC's. Any help would be appreciated.

Hi, Thank you for your post here. 1. From the server itself, can you access the internet? 2. Please provide the tracert output from the client when you attempt to reach an internet site? 3. Please provide the IPconfig /all output from clients and the server. If you have any questions or concerns, please do not hesitate to let me know.

Yes, I can access the internet from the server itself. When i try and do a tracert to say google.com from one of the other PC's it says: Unable to resolve target system name google.com I am able to ping and do a tracert to my server, both the server name and IP address. I can ping and tracert the other PC's both their names and IP addresses. One of the other PC's ipconfig /all output looks like: IPv4 Address: 10.0.0.3 , Subnet Mask: 255.255.255.0 , DHCP Server: 10.0.0.1 (My Server) DNS Server: 173.x.x.x - My ISP's DNS Server. My servers Internal NIC has the following ipconfig /all output: IPv4 Address: 10.0.0.1 , Subnet Mask: 255.255.255.0 , and DNS: 10.0.0.1 The external NIC, has all of my ISP's settings assigned.

Hello smawcpr, There is a mis-configuration at your LAN computers. Ensure that the DNS points to your internal DNS. The Gateway Address must be the ip of your RRAS server. Since your server is a Multihomed DC with DNS, there could be additional sources for a problem. It is highly recommended to use a single home DCs and use a non-DC as RRAS server. Here are some related links: Multihomed DCs with DNS, RRAS, and/or PPPoE adapters http://msmvps.com/blogs/acefekay/archive/2009/08/17/multihomed-dcs-with-dns-rras-and-or-pppoe-adapters.aspx Troubleshooting Routing http://technet.microsoft.com/en-us/library/dd469833(WS.10).aspx Checklist: Installing and Configuring an RRAS Router http://technet.microsoft.com/en-us/library/dd469630(WS.10).aspx Install RRAS http://technet.microsoft.com/en-us/library/dd469845(WS.10).aspx Enable RRAS as a LAN and WAN Router http://technet.microsoft.com/en-us/library/dd458974(WS.10).aspx Kind regards, Harry

Thanks a lot, I finally figured it out after calling my ISP, and Cisco for some more clarification on some of the settings. The fix appeared to be the following, although I'm not sure if it is the best solution: My external NIC is configured with all my ISP settings. My internal NIC, has a static IP assigned of 10.0.0.x, subnet mask 255.255.255.0, default gateway blank, and the dns settings are my ISP's DNS servers. In my DNS settings, I set my internal NIC as the only interface to listen on, and set the DNS forwarders to my ISP's DNS servers. In RRAS I setup NAT using the defaults from Microsoft's KB article: http://support.microsoft.com/kb/816581/en-us the only step I didn't follow, was letting RRAS to assign my DHCP addresses; as I have DHCP setup on my server. I also have a Cisco WAP WRT610N implemented in my network too, in case that further complicates things. The settings for it are as followed: On the Setup tab under Basic Setup I have the Internet Setup set to a static IP. The static info is all the settings from my ISP. On the Network Setup section, I set an IP of 10.0.0.x which I type into my browser to gain access to the login page of the WAP. These are the steps I was given by Cisco because my ISP's modem doesn't do wireless for their business internet; which is what I have. The only other problem I seem to be having now, is extremely slow speeds while surfing the net on my other client pc's. My server seems to have no problems online. I'm wondering if there are any settings I can "tweak" to get some extra performance. My connection from my ISP is only a 6Mpbs connection, but it seems to be reasonably fast on my server. Any help is much appreciated.
