我的iptables配置如下，但内网通，外网ping不通

pastor

我的iptables:

# Firewall configuration written by lokkit
# Manual customization of this file is not recommended.
# Note: ifup-post will punch the current nameservers through the
#       firewall; such entries will *not* be listed here.

注：192.168.2.10 是我的内网地址ip。但内网通，外网ping不通

请赐教。
