我的ISP节stream某些types的stream量。 为了解决这个问题，我想让自己成为一个VPN连接。 IPTABLES是否可以将端口119上的所有stream量（例如）转发到我的vpn接口pptp0？
谢谢

-o, --out-interface [!] name Name of an interface via which a packet is going to be sent (for packets entering the FORWARD, OUTPUT and POSTROUTING chains). When the "!" argument is used before the interface name, the sense is inverted. If the interface name ends in a "+", then any interface which begins with this name will match. If this option is omitted, any interface name will match. PS：端口匹配扩展是：
mport This module matches a set of source or destination ports. Up to 15 ports can be specified. It can only be used in conjunction with -p tcp or -p udp. --source-ports port[,port[,port...]] Match if the source port is one of the given ports. The flag --sports is a convenient alias for this option. --destination-ports port[,port[,port...]] Match if the destination port is one of the given ports. The flag --dports is a convenient alias for this option. --ports port[,port[,port...]] Match if the both the source and destination ports are equal to each other and to one of the given ports.
