使用 IPTables 让 FTP 工作

如果我停止 IPTables 服务，我的 ftp 服务器将按预期工作。但是，启用后我无法连接（在进行身份验证之前）。

# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

ACCEPT     tcp  --  anywhere             anywhere            tcp dpt:ftp

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere            tcp spt:ftp-data
