How to set my OpenWrt routers DHCP to give /32?

How can i set my OpenWrt 10.03 router to not to use 192.168.1.0/24? instead, use a /32 mask, so every client, that gets an ip from the DHCP server just can't sniff the network traffic - it would be a great security feature to safely use e.g.: FTP!

On the wireless side this is done with WPA settings. On the wired side, I think you would need to set up a VLAN per port. Then you can setup a /30 or /28 for each port. /32 addresses are point to point, and I don't think you they will work with DHCP.

How about going to LuCI administration->network->DHCP->additional filed->IPv4 netmask->add?

There you should be able to set up the netmask. I think that the correct setting should be 255.255.255.255. Please do report results!

@user62367 Interesting. I'll check settings on my router and see what can be done. – AndrejaKo – 2011-03-07T17:05:21.923
