Is there a way (such as an iptables match) that allows one to specify
more than one IP address for one rule? I have in mind something like
the multiport patch -- allowing the user to specify multiple tcp / udp
ports per rule. For example, I have the following ruleset that I would
like to convert into one rule:
iptables -N BADGUYS
iptables -A BADGUYS -s 192.168.10.1 -j RETURN # 192.168.10.1 not bad
iptables -A BADGUYS -s 192.168.10.0/24 -j DROP
iptables -A BADGUYS -s 192.168.11.2 -j DROP
iptables -A BADGUYS -s 192.168.11.3 -j DROP
iptables -A BADGUYS -s 192.168.11.6 -j DROP
I would like something like
iptables -A BADGUYS -m multiip --srclist
[!192.168.10.1,192.168.10.0/24,192.168.11.2,192.168.11.3,192.168.11.6]
- -j DROP
