Hi Larry, I don't quite understand why if you have open ports you can't the internet but we'll leave that for another time.
Does this monitoring software use WinXP? You have a static ip address that your ISP assigns you. That is your modem's address. The modem plugs into your router which provides a hardware firewall for your network and lets each of your computers access the internet. Depending on how your linksys is configured, you local computers have internal IP addresses that are fixed or assigned by the router's DHCP. If you are using DHCP you can determine each computer's IP address by typing ipconfig /all into a command prompt window on the computer. If your router always assigns the same address to each computer you can leave the DHCP on. If it changes them when it's rebooted you may have to go to fixed IP addresses for your network because you are going to have to use machine 2's IP address to set this up. If you have to switch to manually assigned IP addresses, use the same range 127.xxx or 192.xxx that the router uses. I would make sure that computer 2 can access the internet before you start trying to implement the monitoring software. Make sure the local area connection on computer 2 is configured properly with the correct access point and dns data. Once you get computer 2 to access the internet you have to get the computer to appear to the outside world like it isn't behind a firewall. You can do this in two ways. One is to use the DMZ function of your router and put the ip address assigned to computer in the DMZ info on your router. This puts computer 2 outside the firewall and any one accessing your bellsouth static IP will see that computer. You will need to put a good software firewall like zone alarm on computer 2 to provide some security and then set it to allow the monitoring software to access to the internet. The second way to do this is to try the port forwarding feature of your router. This way forwards specific ports to computer 2 and only puts those ports specified outside your firewall. I think you would still need to install a good software firewall on computer 2 just to protect those ports from abuse. I'm not sure why linksys couldn't help you on this. It's a pretty common arrangement. So get your linksys manual out and take a look at the DMZ and port forwarding features. Let me know how it goes.

Let me explain the situation first. I have computer one which is my shop computer with XP on it. Computer 2 is used only for a NV 3000 4 camera surveillance system and also has XP. I was told that to watch the DSS (Digital Survaillance System) on the internet I must have a Static IP which comes from Bellsouth my ISP. The instructions say that 6 ports must be opened. I also found out that due to the ports being opened I would not be able to access the internet from computer 2. (This was my original problem and I did not know I would not be able to use the internet.) Both computers are behind a linksys router, (WRT54G)and then connected to the BellSouth Westell DSL modem. The connections are with cat 5 cables. My question are as follows; 1. Should my computer 2 be assigned the Static IP of 74.xxx.xxx.xx? 2. When I open the ports of both the modem and router must I be on computer 2? Or are these ports open to both computers? 3. At present for some reason my router is connecting to the 74.XXX.XXX.XX now and when open my browser and type in 74. number I go to the setup for the router! That does not seem correct to me. Hope this is understandable as I am very new at this. LarryBrowning K & L Electronics ============= PCWorks Mailing List ================= Don't see your post?
