If the main purpose of Walled Garden is to make it easier for CS to diagnose problems by logging into the modem, how does it work if a modem is in the bridge mode?
It doesn't work in Bridge Mode AFAIK. Walled Garden is actually known as TR-069.
Broadband Forum (formally the DSL Forum) TR-069 and its extensions (TR-098, TR-104, TR-106, TR-110, TR-111, TR-135, TR-140, TR-142)* Frequently Asked Questions
TR-069 - CPE WAN Management Protocol Whitepaper
How it works in Router Mode:
The Speedstream 4200 comes with a Customer Premises Equipment (CPE) WAN Management Protocol (CWMP) agent enabled (at least in the Optus firmware version of the router). This agent periodically attempts to connect to an ISP server which can remotely configure the router to your ISP's desire. You may have seen an entry in your system log or syslog similar to the following one which indicates that it is active:
2008-08-17 00:18:01 E | CWMP |CWMP agent cannot reach the ACS named acs.optusnet.com.au:1111/ACS-INTF. Retry in 10 seconds
This is what it looks like in the 4200 Walled Garden system log. Look at the CWMP line entry next to the last entry.
