My guess is that hop 7 is home of a firewall of some sort. I don't have
any recollection of one that would act this way, perhaps it's internal
rule processing causes it to RST connections when it expires ttl. I
don't know, perhaps another list member would know what device or
firewall software would behave in such a manner.

Regarding the port number, my guess is that port 2443 is the 2nd SSL
server 2 + 443 (443 = SSL). Nmap simply uses the common ports database
to guess what service generally resides at the open port it found. For
instance, if I ran my FTP server on port 22, nmap would detect it as an
SSH server. I think there is a switch to have it grab the banner for
you, but I have not used this feature.
Hope that helps.
