Ahem..... Hitman, can we make this easy..... please..... You have made some, unqualified staement that make your currebt setup confusing, to say the least.....

A 192.168.x.x address cannot be contacted directly across the internet... so you can tell us those addresses.... the other address, 68.51.x.x, is your public address on the router itself.... Don't tell us that, just call it the "public address".

On the machine that is currently working:-

1. If the IP address of the working machine is a 192.168.x.x address then look at it's configuration and duplicate it on the other machine _if_ it says "obtain IP address automatically" and "obtain DNS automatically", (or words to that effect).

3. If it is your "public address" you have miswired your router/network. If that is the case unplug everything. Take the cable from the modem the ISP supplies and plug it into the WAM port of the router. Take the cables of the two computers and plug them into the ports numbered 1, 2, 3 or 4...... Set both the computers to "obtain IP address automatically" and "obtain DNS automatically", (or words to that effect). Shut down all the devices for two minutes. Power up everything in this order:-

1: Cable modem, (provided by your ISP). Wait 2 minutes.
2. Linksys router..... You bought this one.... wait 1 minute
3. fire up the two boxes.....
4. Surf that pr0n.....
