Ftp Alg. FTP主动模式和被动模式（3）NAT对FTP的影响 NAT ALG 向往自由的独行者 博客园 ALG - It is recommended to enable Application Layer Gateway (ALG) because ALG allows customized Network Address Translation (NAT) traversal filters to be plugged into the gateway to support address and port translation for certain application layer "control/data" protocols such as FTP, TFTP, H323 etc The FTP ALG profile supports both active and passive modes, where data connections are initiated either from an FTP server (active mode) or from a client (passive mode)

So the firewall needs an ALG module that snoops on FTP commands and automatically adds the necessary rules As a result, when addresses and ports are rewritten, the TCP sequence number might be changed, and thereafter the NAT service needs to maintain this delta in SEQ and ACK numbers by performing sequence NAT on all subsequent packets You can transfer files using the FTP protocol by configuring an LSN pool, configuring an FTP profile, and then assigning the LSN pool and FTP profile to a virtual server..

As a result, when addresses and ports are rewritten, the TCP sequence number might be changed, and thereafter the NAT service needs to maintain this delta in SEQ and ACK numbers by performing sequence NAT on all subsequent packets ALGs supports the applications such as Transfer Protocol (FTP) and various IP protocols that use the application layer payload to communicate the dynamic Transmission Control Protocol (TCP) or User Datagram Protocol (UDP.
