Is 192.168.0.0/28 correct? Does it agree with what ifconfig(8) shows
the settings on your network interface to be?
If you're using RFC 1918 address space on a private network, there's
generally no need to subnet as tightly as /28. Most people would use
/24 in that situation.
In case you can't immediately remember how to convert between all the
formats you can express a netmask as:
/28 corresponds to a netmask of 0xfffffff0 or 255.255.255.240
/24 corresponds to a netmask of 0xffffff00 or 255.255.255.0
Cheers,
Matthew
