Handling clients with static IP from different network

Question

I have to set up a wireless router (with openwrt) whose dnsmasq DHCP server is configured to issue addresses on the 10.109.0.0/16 network. Now the challenge is that there are a few machines on the network who are unfortunately statically configured to have IP addresses in 192.168.1.0/24. Is there a way to make those 192.168.1.x machines reachable from machines on the 10.109.x.x network?

Or would that be too much trouble and it would be a much easier solution to try hard and change either the network of the 192.x machines or maybe reconfigure the router to work on the 192 network?

Answer 1

While a bit messy, having two subnets on the same link shouldn't cause any problems.

Just configure the router's LAN interface to have IP addresses 10.109.0.1/16 and 192.168.1.1/24 (or whatever gateway those machines expect).

Of course, DHCP will always give addresses out of the main subnet (unless you add static leases for individual off-subnet hosts).
