Get Specific DHCP IP from each LAN Port, any suggestions?

[kasome]

Hi,
I am new to openWrt and have some problems with openWrt, any suggestions will be welcome.

For port forwarding reason, i try to make device (e.g. IP Camera) to get specific DHCP ip from each LAN port, for example,

Port 1 LAN -> Get IP = 192.168.0.101 from DHCP
Port 2 LAN -> Get IP = 192.168.0.102 from DHCP
Port 3 LAN -> Get IP = 192.168.0.103 from DHCP
Port 4 LAN -> Get IP = 192.168.0.104 from DHCP

wireless LAN -> Get any IP between 192.168.0.105 and 192.168.0.200

should i just use configuring or try to modify and build my own OpenWrt firmware ?

Add static IP leases based on the device's MAC, to the DHCP.

Bring them up one at a time after setting your DHCP range.
