xfinity deletes port forward

xfinity deletes port forward. Why? I don't know, third base.

setup: bridge interface on headless box for multiple VM's

issue: xfinity cannot "see" the bridge device as a "connected" device

Solution: make some noise on the interface by ping speedtest.xfinity.com, wait for the app to update.

results: interface goes from "disconnected" to "connected"

note: as soon as the ping command terminates the app will say something like "connected 7 minutes ago"

Should ping speedtest.xfinity.com continue indefinitely to maintain a status of connected or a cron job to run for several hours each day?

fact:

device MUST BE connected (show in list) to setup a port forward

xfinity requires a minimum of 2:00 minutes of noise to stay on the "connected" list.

i.e. ping -c180 96.96.229.183 >> /xfinity.txt && echo "completed at $(date)">> /xfinity.txt

xfinity will remove device from connected list 1:00 minute after ping terminates, so ping every 5 minutes.

i.e. crontab -e */5 * * * * pingxfinity

note: if the device shows "disconnected" wait 2 minutes, close the phone app then try again.

but ping continuously just for fun.
