Don't understand [0:0] iptable syntax
- by artaxerxe
I'm struggling with some iptables rules. I'm a newbie in iptables. I found some resources where I get the following command related to iptables. This is stored in a file that will be executed.
[0:0] -A PREROUTING -s 10.1.0.0/24 -p tcp -m tcp --dport 81 -j DNAT --to-destination 10.1.0.6:3128
Can anybody explain me what does [0:0] mean? Also, some link related to this in iptables are welcome.
Thanks in advance!
P.S. If you need more rules, just let me know.
