Firewalls are essential for security reasons, so that you can expose more
services behind a network than to the outside world. As well as restricting
incoming calls, they often restrict outbound connections. For example,
outbound connections to port 80 (HTTP) may be blocked to encourage use of an
HTTP proxy server (see below), outbound connections to port 143 (IMAP)
blocked to stop people connecting to external mail servers. You need to
assume that there will be firewalls in the network, between SOAP client and
server, and so callbacks from server to client are not going to be
possible.examines every packet and only allows packets of the current TCP
conversation in, and is even better. Firewalls are essential for security

It looks like some more text got in twice on

in the section on Firewalls in the "Core TCP/IP Concepts section"
