You got it. When I connect my modem directly to my computer, LiveShare works. When I get my internet connection from my router, it doesn't work. I spent the better part of 2 hours on the phone with 3 different Linksys agents trying to get the Port Fowarding set up correctly and by the end, I had no internet connection at all.
By the way, how do I know what port to forward? I tried 10080.
Are you making good use of LiveShare? I'm wondering if I should continue to invest time in getting this set up or if I should just cut bait and get set up with a Snapfish or some other photo sharing service. What'd you think?
