Hello all,
I have a question on IPtables:
The following is for a LAN based IP address:
iptables -A FORWARD -p tcp -s 192.168.1.0/24 -i eth0 -j DROP
iptables -A FORWARD -p udp -s 192.168.1.0/24 -i eth0 -j DROP
Can this be used for WAN IP's?? Something like this:
iptables -A FORWARD -p tcp -s 68.68.68.68 -i eth0 -j DROP
iptables -A FORWARD -p udp -s 68.68.68.68 -i eth0 -j DROP
And also can wild cards be used?
iptables -A FORWARD -p tcp -s 68.* -i eth0 -j DROP
iptables -A FORWARD -p udp -s 68.* -i eth0 -j DROP
Thanks in advance,
~WILL~
No reason why not. I wouldn't use wild cards, but I would use CIDR
notation (xxx.xxx.xxx.0/24) for wild cards; e.g.
iptables -A FORWARD -p tcp -s 68.0.0.0/8
Thank you Bill :) I appreciate it.
