I setup my IP170D yesterday.
I registered my device and contacts.
I can access it from my LAN - no problem there.

On my router, I forwarded external port 80 to the IP address of my IP170D
However the status on the IP170 Home page (under envisalert) is always offline.
I clicked on login to account and I do log in and can can see my security device but is inactive (doesn't receive status and sending commands does nothing)

I tried accessing the module from the internet (via my blackberry) and I can connect and monitor/control my alarm

I'm sure there's some feature in my router (linksys E2000) that I need to turn on or some basic step that I misssed.
IP170D firmware = Firmware Version: 001.000 17 - Wed Jul 06 14:19:19 2011
Hope someone can help. Thanks.
