Basic explanation of what the Bridged AP mode is and the configuration of RB in Bridged AP mode is given here. Configuration specific to our network is given below.
File: /etc/config/network 

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

config interface 'lan'
        option ifname 'eth0'
        option type 'bridge'
        option proto 'static'
        option ipaddr '10.107.91.232'
        option netmask '255.255.224.0'
        option gateway '10.107.95.250'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '1 2 5'

Notice the 'option type bridge' written in boldface. Here, it is assumed that the IP addresses are assigned in a static manner. If a DHCP server can lease IP addresses to the RB, then replace 'option proto static' with 'option proto dhcp' and delete (or comment) the next three lines.

File: /etc/config/wireless

config wifi-device  radio0
        option type     mac80211
        option channel  1
        option hwmode   11g
        option path     'pci0000:00/0000:00:14.0'
        # REMOVE THIS LINE TO ENABLE WIFI:
        #option disabled 1

config wifi-iface
        option device   radio0
        option network  lan
        option mode     ap
        option wds      1
        option rts      0
        option ssid     Openwrt
        option encryption none

Note:

  • Wireless Distribution System (WDS) has been enabled (option wds 1). This is necessary in the Bridged AP mode.
  • The RB is configured as an AP (option mode ap). The RB can instead be configured as a client or station (option mode sta).
  • The option rts 0 works only for madwifi based system. We have used ath5k drivers. So, though RB does not throw an error, RTS mechanism doesn't actually work.
