如何查看iptables的log

大概是我的防火墙rules设得太死了，现在有些应用都出不去了。各位有啥好办法能让我看到iptables的rules。

TARGET EXTENSIONS
       iptables can use extended target modules: the following are included in the standard distribution.

   LOG
       Turnonkernel logging of matching packets.When this option is set for a rule, the Linux kernel will
       print some information on all matching packets (like most IP header fields) via the kernel log (where it
       can be read with dmesg or syslogd(8)).

       --log-level level
            Level of logging (numeric or see syslog.conf(5)).

       --log-prefix prefix
            Prefix log messages with the specified prefix; up to 29 letters long, and useful for distinguish?
            ing messages in the logs.

       --log-tcp-sequence
            Log TCP sequence numbers. This is a security risk if the log is readable by users.

       --log-tcp-options
            Log options from the TCP packet header.

       --log-ip-options
            Log options from the IP packet header.
