Currently we are using an Untangle router/gateway of 192.168.10.254. The Regular subnet mask is 255.255.255.0.
I am planning to change the subnet mask of the network to 255.255.254.0 to allow for a few more IP addresses..... which will open up the range of 192.168.11.0-254.
If I change to 255.255.254.0, can I still keep the original 192.168.10.254 for my Untangle router/gateway?
Thanks!
