would
have otherwise restricted the traffic for not meeting
its limited filter criteria.
Usually allowing client applications to use dynamic
ephemeral TCP/ UDP ports to communicate with the
known ports used by the server applications, even
though
a
firewall-configuration
may
allow
only
a
limited number of known ports. In the absence of an
ALG,
either
the
ports
would
get
blocked
or
the
network administrator would need to explicitly open
up a large number of ports in the firewall; rendering
the network vulnerable to attacks on those ports.
In the default ALG settings, the following protocols
have
