You know how NGINX can redirect queries for www.domain1.com:80 to an internal ip, and www.domain2.com:80 to another internal ip even though they have the same external ip?
I know the domain is in the HTTP header, and that's how NGINX does that, but is there a software that can do the same thing but for things other than HTTP? Like maybe something that recognizes the type of traffic as FTP, or SSH, or anything else, and redirects it or treats it according to your own rules?
I know firewalls can recognize traffic types (SPI), so I figure there's probably a piece of software out there that can do that... maybe it won't be able to be name-based, but the result would be the same... You can have multiple things point to the same external IP but get redirected to the right internal IP...
that would be awesome...
