Hi all, This my scenario: We have two networks in our lan: 10.0.0.0/24 and 192.168.1.0/24. Actually the networks are separated. The 192.168.1.0/24 network contains some hosts that ip can not be changed. The goal: We want redesign the network and communicate with both networks without routers. I thougnt about changing the netmask for 192.168.1.0/24 in 192.168.1.0/22 (1022 hosts) and change IP's in the 10.0.0.0/24 network in 192.168.2.0/22. Is that correct? have you other suggestions? Thnx Andrea Gail

The way you worded your message is a bit confusing, but yes it will be fine (although they obviously will have to be connected on the same layer-2 network to communicate). Once you make your changes, the 192.168.0.0/22 network will cover the range 192.168.0.0-192.168.3.255 and everything in between will be in the same subnet. The devices will all ARP directly for each other and happy communication will ensue. Cheers, Matt
