Hi, I have this configuration.
Comcast modem -> cradlepoint -> our router
The external traffic is not reaching our router. Traffic generated by our network works normally.
If I bypass the cradlepoint (i.e. Comcast modem -> our router) everything works as expected, i.e. generated external traffic reach our router.
Note that I did disable the Comcast modem WiFi since we are not using it anyway.
I did try to log in to the cradlepoint but it refuse to accept the default password (the one printed on the label below the cradlepoint) so I don't know if there some settings I can change to allow external traffic to pass thru or set up a firewall.
Any idea ?
