Hi Mark, I've had this problem for over 12 months and its annoyed me intensely that *any* 192 series public IP number has been impossible to connect to. In fact I *almost* purchased another router (but didn't).
Your solution will work, of course, but for me, I couldn't bring myself to change my manually allocated LAN addressing on my home network (6 machines). I've just realised there is a simpler way - that has no drawbacks (as far as I know) - at least for a network that doesn't have thousands of machines.
Why not simply change the *mask* in the router rather than the LAN IP series?
ie mask change from 255.0.0.0 ....... to ......... 255.255.0.0
The router will then place the Adobe 192.150 series of IP numbers outside the internal LAN allocation - turning it into a public IP number. I've just done this, and - at last - I can access 188.8.131.52 (Adobe Reader 9).
Thanks for your post - it was the trigger I needed to turn on my lightbulb :-)
