Here my Openwrt running on atheros7k/9k with only one ethernet interface, the main logic as below,
Now this setting works perfect to routing between wifi and ethernet world. The bridge setting as below,
config interface 'nw1' list ifname 'eth0' list ifname 'r1_mesh1.1' option vlan_id '1' option type 'bridge' option reqopts '66' option netmask '255.255.255.0' option igmp_snooping '0' option ip6assign '60' option name 'infrastructure' option enabled '1' option priority '0' list dns '0.0.0.0' list dns '0.0.0.0' option hostname 'xxxx_FFFF' option proto 'static' option ipaddr '172.16.3.118'
Now I need to add an another virtual network interface, not related with wifi ap, but just a network interface which could hold its own static ip or DHCP. As above, the traffic would be through the bridge as well. Any idea please kindly let me know. Thanks advance.
