The official ports  TCP 5222 and TCP 5269  are listed in RFC 6120   Contrary to the claims of a previous answer  XEP-0174 does not specify a port   Thus TCP 5298 might be customary for Link-Local XMPP  but is not official   You can use other ports than the reserved ones  though   You can make your DNS SRV record point to any machine and port you like   File transfers  XEP-0234  are these days handled using Jingle  XEP-0166    The same goes for RTP sessions  XEP-0167    They do not specify ports  though  since Jingle negotiates the creation of the data stream between the XMPP clients  but the actual data is then transferred by other means  e g  RTP  through that stream  i e  not usually through the XMPP server  even though in-band transfers are possible    Beware that Jingle is comprised of several XEPs  so make sure to have a look at the whole list of XMPP extensions

The ports required will be different for your XMPP Server and any XMPP Clients   Most  modern  XMPP Servers follow the defined IANA Ports for Server-to-Server 5269 and for Client-to-Server 5222   Any additional ports depends on what features you enable on the Server  i e  if you offer BOSH then you may need to open port 80   File Transfer is highly dependent on both the Clients you use and the Server as to what port it will use  but most of them also negotiate the connect via your existing XMPP Client-to-Server link so the required port opening will be client side  or proxied via port 80

According to Extensible Messaging and Presence Protocol  Wikipedia   the standard TCP port for the server is 5222   The client would presumably use the same ports as the messaging protocol  but can also use  http  port 80  and https  port 443  for message delivery  These have the advantage of working for users behind firewalls  so your network admin should not need to get involved
