По умолчанию Adobe Flash Media Server использует порт 1935 для RTMP (протокола обмена сообщениями в реальном времени). Этот порт был назначен Adobe для сервера Flash Media Server IANA (Управление назначением номеров в Интернете).
Если используется брандмауэр, этот порт необходимо открыть. В противном случае сервер должен быть настроен на использование другого порта в теге Adaptor.xml. Ниже показано, как выглядит запись по умолчанию для тега:
<HostPortList>
<!-- Specifies what IP address and port(s) to bind to. This is specified -->
<!-- as a string in the form"<ip>:<port>,<port>,...,<port>". -->
<!-- For example, "127.0.0.1:1935,80,443". This says to bind to the IP -->
<!-- address of 127.0.0.1 on ports 1935, 80, and 443. You can bind to -->
<!-- any IP by not specifying anything in front of the colon. -->
<!-- For example, ":1935,80,443". This says to bind to any IP on ports -->
<!-- 1935, 80, and 443. If no colon is found, the data is assumed to be -->
<!-- an IP address, and will bind to port 1935 as the default. -->
<!-- For example, "127.0.0.1". This says to bind to IP 127.0.0.1 on port -->
<!-- 1935. If a colon is found but no ports are specified after it, port -->
<!-- 1935 is used as the default port in which to bind. -->
<!-- For example, "127.0.0.1:". This says to bind to IP 127.0.0.1 on -->
<!-- port 1935. If you wish to bind to multiple IP addresses on this -->
<!-- adaptor, specify additional <HostPort> tags; 1 for each additional -->
<!-- IP that you wish to bind to. NOTE: Another adaptor may also try to -->
<!-- bind to the same IP-port combination resulting in a conflict. This -->
<!-- is considered a conflict since it is undesirable to have more than -->
<!-- one adaptor listening on the same IP-port pair. To resolve this -->
<!-- conflict, the first adaptor to do the bind - wins. A warning will -->
<!-- be logged indicating that the specified IP-port combo is in-use. -->
<HostPort>:1935</HostPort>
