That is the 'normal' way to bridge these modems, the working-mode drop down (that Shaw removed) bridged or gateway. I believe working_mode 0 is Gateway mode. Power reset no, reset button yes, firmware update, maybe.
Firmware update could change the field names as well.
I put a copy of this on my webserver, so after logging into your modem with cusadmin going to this page and then Submit, should bridge your modem as well.
To make it easier for others, instead of having to create/open a local file.--
