Your idea of subnet masking is right.  255.255.255.0 (/24) is
192.168.1.0 - 255 (0 being network 255 being broadcast)
So, everything being blocked would be specific to firewall rules.
Maybe check your firewall rules?
Maybe posting your ipchains or whatever other rules would spur info
from someone else.
