I see that I might have used the wrong word here. I am use to calling
them TCP splitters, but I see that the devices are also referred to as
transparent TCP proxies. Anyhow, they are still transparent, but they
violate end-to-end (even though I guess that is pretty common
now-a-days).

What I mean by the port-comment is that only connections to some ports
are proxied/split. For example, one of the operators in Norway only
proxy port 80, so any HTTPS transfer risk getting stuck after a
temporary disconnect.
