hi!
PS> ipchains -A input -p all -s [your.domain/netmask] -d PS> aaa.bbb.ccc.ddd/netmask -i [internal eth] -j DENY -l
what is the netmask of any domain in the i-net?
netmask is eg 24 Bits long = 255.255.255.0 If you don't know what to do with this information, read net3-howto to learn more about the internet protocol. You can also read this 3Com document, which indeed describes very good the use of the Internet Protocol: http://www.3com.com/nsc/501302.html and then you should read RFC 791 on www.rfc-editor.org
