November 9, 2009 at 09:40:54
Specs: Windows SBS 2003
I have to NIC cards on SBS 2003 one NIC is for the WAN with static IP information from my ISP and is connected directly to the DSL modem, the other NIC is for the LAN with IP and is connected to a switch, server and client has access to internet but client do not have access to server, I tried to run the wizard "http:server/connectcomputer" but gives me a message "Make sure that only one network adapter is enabled and that it is connected to the SBS", I am going to get a wireless access point from Cisco to use other client wirelessly. Please help me cause I have spent two weeks and I can not make it work. Thank u

I didn't see you mention anything about configuring RRAS.

No rras no routing between nics.

Hi thank u for ur reply, no I don't know about RRAS, I just followed the wizards, as I said both server and client does have access to internet but client is not able to connect to intranet, somebody was telling something about the NAT but I do not have any knowledge about this or RRAS, if could help me with the information to get my client computers connected to the server will be greatly appreciated.
I just finished configuring remote access and I tested and from a client computer not connected to the network, used a different ISP account I was able to connect to the server using the NIC card with IP address from the scope. I mean that from client I used the remote workplace and entered the IP address of my LAN adapter.
Thank you

Given your situation I see no reason for you to be routing thru your server for internet.

Normally the workstations point to the router for internet gateway.
If you are running Active Directory then you need them to point to the server for dns and in dns server forwarders tab you put the isps dns servers ips.

use only one server nic
don't run rras

If my server is down then the clients will not have access to the internet right?, I am not using an external router and I am not planning to unless I really need it and you recomend me to do so. The dns on my LAN card is the same as the IP address of this card "LAN", that is the way I set it up; I do not know how or where to input the dns and the forwarders you mention. Could you also tell me why my clients are not connecting to the server? and how implementing your solution will work?.
Thank you again for your valuable time.

I forgot to tell you that our biggest concern is security and that is the reason why we are trying to use both cards, I am trying to avoid intruders specially now that we have to use wireless access points and wireless client computers. Any recomendations to make it more secure is helpfull for us.

put in a router/firewall. That is the first step in security.

secure your wireless with a strong encryption key.

Have staff practice safe computing

U mean put a router/firewall instead of the switch and could be a wireless from Cisco?, turn off the DHCP from router and use it just as a firewall?.
This is not going to solve the problem I have because even if I have a router still the client computers are connceted to the router or the switch but I can not configure the Lan because clients are not connecting to server, How do I do that, any suggestions to get step by step information?., my concern besides security is to get the client computers conected to the LAN.

standard physical configuration
Internet<>router/firewall<>switch<>server and pcs

Logical configuration
Internet<>router/firewall is gateway - dhcp is off
server provides dhcp in the correct amount and subnet

So lets say gateway is
Server is at
Server provides dhcp to 192.168.11 to 25 which provides 14 hosts (pcs)

dhcp would provide these details gateway dns
192.168.1.? ip address for the workstation

You load ms dns server on the server
You configure dhcp to do dynamic updates to dns
You configure dns forwarders to that of your isps dns servers.

This is a standard basic configuration.

Now to the server. You don't say what you are running for server or if you want to do Active Directory. Please answer.

Thank you, server is running active directory, router should have Static IP configuration from ISP provider instead of NIC card from server?
this is my set up:
WAN NIC card
IP: 208.13.310.2
Gtwy: 208.13.310.1
Primary DNS:
Secondary DNS:

LAN NIC card
Gtwy: blank
Preferred DNS:

Server DHCP scope to 99

Internet<>server WAN card<>switch<>server LAN card
client pcs connected to switch getting IP from server thru LAN card as gtwy and subnet

This is exactly what I have, server runs active directory and this is where I am stuck.
Thank you for your concern and help.

Internet<>server WAN card<>switch<>server LAN card

wrong which is why this is not working

Internet<>server WAN card<>server<>server LAN card<>switch<> pcs

I will say again THIS IS NOT THE PROPER CONFIG. It puts your server at greater risk of being hacked.

If you wanted to do this you need ISA server and the config would look like this

internet<>wan card<>server running isa<>lan card<>router<>switch<>servers and pcs

I say again don't do this. Do the standard config with a router firewall as gateway.

Thank you, I will try, I'm going to get a router to work on configuration, one question, can the router be wireless capable or should I use a wired router and add an wireless access point later to the router.
Thank u
