Hello Eric
Yes its possible. several ways.
1 IP Chains
2 hosts.deny
3 hosts.allow
look at the 3 options.
I believe adding
All: * to hosts.deny to block all IP's
and adding to hosts.allow
All: your Ip range here like 24.4.0
would allow all access from your network.
Ip Chains is a package that blocks all IP's except ones in the excluded
list.
Also Install Portsentry 1.0 http://www.psionic.com to keep people from
scanning for open ports and looking at Software Versions if the do get in
through a hacked IP.
Good luck.
