求助vsftp问题！！！！！

fly-ing

环境：
服务器使用内网ip（有放火墙），通过路由连接外网，客户机也是内网ip通过路由连接外网，并且可能有防火墙，听说需要通过被动传输才可以连接上去，可能是因为服务器防火墙问题，ftp可以建立21端口连接，但是过一会就会因为数据连接超时而连接失败
操作系统版本：RedHat AS4 ftp服务器：vsftpd

放火墙规则：
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT ipv6-crypt-- anywhere anywhere
ACCEPT ipv6-auth-- anywhere anywhere
ACCEPT udp -- anywhere 224.0.0.251 udp dpt:5353
ACCEPT udp -- anywhere anywhere udp dpt:ipp
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:https
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:http
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ftp
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited



不会设置放火墙，我想应该就是放火墙问题，希望可以给出设置放火墙的指令

谢谢

在console下输setup，之后选防火墙，可以用一个工具来设。
