Sorry my English.
I use wr841n as AP (not router). OpenWrt Attitude Adjustment 12.09-rc1
AP (br-lan) has IP 192.168.5.89/24. WAN port is empty.
Users has IP from diferent nets, some 172.16.0.0/21, 192.168.155.0/24, 192.168.156.0/24 and more.
How can I automatically learn ARP?
Now I do this
ip neigh add 192.168.157.151 lladdr 5C:AC:4C:71:CB:36 nud permanent dev br-lan
but it is inconvenient
Perhaps there is a way to do this automatically?
