Should be a totally different scope, not just an other netmask, also an other network. Then the routers can do a lot for you, now you only have to hope your routers can coop with the stuff. If you use a totally different network, then just connect the same router with a second port to the same network. configure this new port as one (the gateway) of the new network and off you go. > current IPs are running > 192.168.60.1 - 255 the Wild guess: subnet was 255.255.255.0? That makes the next pre-defined (not for host usable) addresses: network: 192.168.60.0 broadcast: 192.168.60.255 The available host range: 192.168.60.1 - 192.168.60.254 prefered hosts (not requred, its just most tools provide this as default values once the address and netmask of the above network is defined): gateway: 192.168.60.254, network services (dns, dhcp etc): 192.168.60.1 > new scope is 192.168.61.1 - 255. and subnet mask 255.255.248.0 That makes: network: 192.168.56.0 broadcast: 192.168.63.255 The available host range: 192.168.56.1 - 192.168.63.254 with the prefered hosts on the boundaries as before. It is perfectly acceptable to use other addresses for the gateway and the network services, You see, the network address and the broadcast address of one network are host addresses on the other network. > When I try to connect with VNC from my PC (old > scope) to a new PC (new > scope) it fails. I've changed my subnet mask to > 255.255.248.0, but it stills fails. Is there anyway around it? As long as a machine thinks it is on the old network, all addresses outside this network are forwarded to the defined gateway. No problem from this host. If the gateway is already configured for the new network, bad luck, it just ignores the call since the message is already on the proper network, no need to `gateway` the message. If the gateway is still configured for the old network, it depends on the routing tables. If the routing tables are still in the old network state, bad luck, your message goes out to the other networks, but not back to the network with the double configuration. Only if the gateway has its network-connection configured for the old network and has updated routing tables to route messages to the new network (but not in the old network) back to the old network, then you might get a connection. Hence, best to do a big-bang update of all machines: proper operating systems can do that on the fly. Or if you want to do it silently, do it to an other network addres, not one that includes the old network.
