Well, here's an update... I spent over 1-1/5hours on a call with
Linksys tech support. They basically told me that my computer was
dropping the connection to the Linksys (but that the Linksys was still
holding the connection to the ISP). So, I went back to the ss5200 as
my pppoe unit. I took the linksys out of the loop and got my vnc up
and running again.
Long story short, the linksys was changing it's ip (192.168.254.1 to
.2, to .3 randomly) and the forwarded ports on the ss5200 went to the
wrong ip. So I set the linksys to static ip and all is well!! (so
far! :) )
Thanks for the help
