In this case, you need to map port 2121 to the FTP protocol. After port mapping, the NAT server can identify the FTP packets that use port 2121 and send the FTP packets to the FTP server. In this way, users can access the FTP server. The device provides ACL-based port mapping and ...
在这样的场合则需要使用端口映射功能把2121端口映射成FTP协议,则NAT服务器就把2121端口的报文识别为FTP协议报文转发给FTP服务器,实现用户对FTP服务器的访问。 设备对端口映射的支持都是通过ACL来实现的,只有匹配某条ACL的报文,才会实施端口映射。端口映射使用基本ACL(编号2000～2999)。端口映射在使用ACL过滤报文时,使用...
这条我想应该是应用在接口的出方向，阻断ftp服务器回应202.101.2.1的包。但光看这句，202.101.2.1的请求时可以到达ftp服务器的。deny 禁止 tcp tcp协议 source 源地址 10.1.1.1 0 表示单机(host)source-port eq ftp 21端口 destination 目标地址 202.101.2.1 0 表示单机(host)...

目前局域网内的主机可以正常访问Internet(包括公网FTP 服务器),如今在路由器上增加如下配置: Firewall enable Acl number 3000 Rule 0 deny tcp source 10.1.1.1 0 source-port eq ftp destination 202.102.2.1 0 然后将此ACL 应用在GE0/0 接口的inbound 和outbound 方向,那么这条ACL 能实现下列哪些意图?

用户通过NAT服务器访问FTP服务器时,只能使用2121做为端口号。由于默认情况下FTP报文的端口号是21,这时FTP服务器无法将21端口的报文识别为FTP应用。在这样的场合则需要使用端口映射功能把2121端口映射成FTP协议,则NAT服务器就把2121端口的报文识别为FTP协议报文转发给FTP服务器,实现用户对FTP服务器的访问。
