Please log in for more thread options set one up before, but the setup was different than this one. They switched to a new isp with a static ip address. Here is the setup The server's internal network card is 192.168.0.150 linksys gateway is 192.168.0.1 workstations have static ip addresses 192.168.0.xxx with gateway as 192.168.0.1 and dns as 192.168.0.150 and xxx.xxx.xxx.xxx from current ips provider. I am getting confused by the ip addresses and the order of the connections. I have put in a second nic in the server. Should it connect to the switch or the dsl modem/router directly? what should the numbers be on this nic (ip, DNS, etc) The dsl modem has the static ip address as well as the gateway and DNS addresses setup as a bridge. The address of the dsl modem was 192.168.1.1 and I changed it to 192.168.0.3 so I can access it from a workstation. The workstations can connect to the internet directly without the server being on. (not sure why they have it setup this way--could be carry over from former setup with out server) Any help would be appreciated. Thanks. | ||||||||||||||||

First, from the information you provided, the server appears to be used for your WINS/DNS and DHCP. Very rarely do people use the servers as a proxy any longer. (The old MS proxy days....) Internet functionality would not be dependent on it, but without the server you will loose PC connectivity in 5 to 8 days, depending on your DHCP lease time. so don't turn it off, or plan on getting rid of it unless you move the DHCP to a different device. Unless you are going to give all your machine public IP addresses (NEVER RECCOMENDED) then you will need to keep the linksys firewall/ router. Also, why the need for the second NIC in the server? Are you trying to dual home the server to get internet access? You did not state that there was a problem with server access, although you did say that workstation access is fine. In regards to the IP address order you listed on the secondary NIC, I am not sure what you mean. If you mean the different address on the DNS, It looks like you are resolving all internal addresses first and then dropping to the outside DNS as a secondary. If this is what you meant, it would work, personally I would move the secondary DNS to a forwarder in your DNS. Unless the server is doing proxy or some other need for outside resolution its better to have it segmented correctly in case you have to troubleshoot something. I beleive that linksys uses in-house vpn software for most of their VPN access, Quick VPN. I do not know if you current model supports it or not, but you can check the linksys site and see if you can do a firmware upgrade that will allow you to use the Quick VPN software. The setup you listed above seems pretty standard as far as a network model. Modem to Firewall, and then using a differnet non-routable address set internally (NAT) In my opinion, no need to really change anything. If you can upgrade to use the Quick VPN software, you should not have to change anything, but just set up the appropriate route/rule in the firewall and have the users use the Quick VPN software to connect. Hopefully this helps! | ||||||||||||||||
