"And it's example of how painful it can be to set that up as NAT broke the original FTP for a while."
NAT broke FTP for about the 5 seconds it took for one to realise they needed to type in the PASV command - which existed right from the start.
It was in RFC 542 (1973) - pre TCP, and RFC 765 (1980) - first post TCP.
NAT dates from around 1994.
- tonyg 3y agoPASV works around some but not all NAT breakage. There are things FTP can do outside a NAT that it can't do with a NAT around. (Workarounds can be concocted, but NAT really did take away some of the natural abilities of FTP.)
