Here's what I have:
LS-CH500L w/ 1.41 firmware
Belkin F5D8235-4 Router w/ latest firmware
I do not have a domain at home, just a normal home network.
I have set up WebAccess and can access it from any of the computers in my house. I cannot access from work, my wife's work, my parents' home nor a couple of other friends' homes.
At first, had enabled 'auto configure firewall' and made sure UPnP was enabled on my router.
Then, I turned auto configure off and set up port forwarding (9000 to 9000 per Buffalo Tech Support). Rebooted both devices and had several family members/friends (all different locations) try from their home, no dice.
In the webadmin, noticed that the external port was 41532, so I changed port forwarding to 41532 to 9000 and rebooted both devices. Family/friends still could not access.
All the while, I could access from 2 different laptops in my house. The forwarding is set up for both TCP and UDP.
Buffalo TS does not have any further advice.
Any thoughts?
