i went out and bought a book to help me write an iptables firewall and so far it's very helpful. i'm just not clear on some of the terminology. at the beginning of my rc.firewall file, it's asking me to define some things i've never heard of and i was hoping someone here could clarify:
IPADDR="my.ip.address" this i understand to be my ip address: (24.79.xxx.xxx) but what's this? MY_ISP="my.ip.address.range" # ISP server & NOC address range and what are these? iptables -A INPUT -i $INTERNET -d $SUBNET_BASE -j DROP iptables -A INPUT -i $INTERNET -d $SUBNET_BROADCAST -j DROP what's a subnet base? or a subnet broadcast? this is supposed to block a "directed broadcast" what's that? iptables -A INPUT -i $INTERNET -d $BROADCAST_DEST -j DROP that line also makes no sense to me. is this for large-scale firewalls only? do i have to worry about this? -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
