There you go… the 71.x.x.x is the IP assigned by your ISP; it is the external one, the one the world sees.
The 192.168.x.x IPs are assigned by the router internally, for the computers on the LAN. These IPs are not seen by the world. These are the ones we’re talking about setting as static.
To give a brief explanation of what happens… with your ISP, you have only one IP address, one point of contact with the internet. But you’re connecting multiple computers, which would be problematic on just one IP address. Here’s where Network Address Translation (NAT) comes in; this is commonly what a router is used for. It assigns internal IP addresses to the resources on the Network, and serves as a “hub” for the single IP connection to the outside world. The world only sees the Untranslated IP address (ie, the 71.x.x.x) and the network only sees the Translated IP addresses (ie, the 192.x.x.x). If you want to learn more about it, Wikipedia is as good a place as any…
What I’m suggesting is to go (in Windows) to your Network Connections screen, and find the active connection’s icon (will say “Local Area Connection” or possibly “Wireless Network Connection” - not the “1394 Connection”). If you have multiples and you’re not sure which one, right-click and select Status on each - look for the one showing traffic…
Close the Status window, right-click the one you need and select Properties. It will show the Network Interface Card (NIC) you’re using, and a list of items that the connection uses. Scroll down to Internet Protocol (TCP/IP), highlight it, and click the Properties button. On the General tab, select “Use the following IP address” and fill the info in as we discussed earlier. You can leave the DNS server set to automatic. Then OK, and OK again. That’s it. (Remember, on your corporate laptop, you’ll be choosing the Alternate Configuration tab, instead of General.)
This way, your router won’t assign the internal IP address (which it does dynamically, meaning it could be anything in your entire subnet; not necessarily sequential), and your computers won’t be asking it to. This way, you KNOW what the IP addresses of each computer on your network will be, and you can use that to define the trusted zone/network within Comodo.
PS: I hope none of this is too confusing… we’ll take you through it, so anything that doesn’t make sense, just ask.
