Netgear DM200 OpenWRT 21.02.1 bridge configuration

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,

I wanted to share with you the working config I ended with with a Netgear DM200 ADSL/VDSL modem running OpenWRT 21.02.1 as a bridge modem.

As mentioned in the "TOH" page I had to " Fix U-Boot Configuration to Support Larger Kernels".

Here is the /etc/config/network file :


config interface 'loopback'
	option device 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

config globals 'globals'
	option ula_prefix 'fd00:1234:5678::/48'

config atm-bridge 'atm'
	option vpi '0'
	option vci '38'
	option encaps 'llc'
	option payload 'bridged'
	option nameprefix 'dsl'

config dsl 'dsl'
	option annex 'a'
	option tone 'av'
	option ds_snr_offset '0'

config device
	option name 'br-mgmt'
	option type 'bridge'
	list ports 'eth0.200'

config device
	option name 'eth0'
	option macaddr '01:23:45:67:89:0a'

config interface 'mgmt'
	option device 'br-mgmt'
	option proto 'dhcp'

config device
	option name 'br-wan'
	option type 'bridge'
	list ports 'dsl0.832'
	list ports 'eth0'

config device
	option name 'dsl0'
	option macaddr '12:34:56:78:90:ab'

config interface 'wan'
	option device 'br-wan'
	option proto 'none'

ISP is Orange in France, connection is VDSL, you may have to change VPI and VCI and dsl0 VLAN too.

All working fine with a pfSense router using VLAN 200 to manage the modem.

Hope this can help !
