style='font-size:9.0pt;font-family:Arial;color:black'>Several Internet services
use multiple channels to handle the service control and data communications.
For instance, FTP uses one channel to open initial communications from the
client to the server, and the server opens a separate channel back to the
client to send the actual file transfer traffic. Similarly, H.323 uses one
channel for initial call setup, and other channels are negotiated from the
initial connection to carry the actual streaming media, such as audio traffic
in an IP telephony connection.<o:p></o:p></span></font></p>

Subsequent connections for the session are dynamically opened for the session,
based on <span class=SpellE>SPI's</span> scrutiny of the connection setup. This
is usually known as "<span class=SpellE>fixup</span>". If an outbound
ACL is configured on an interface to restrict network access policy, it must
only account for the initiating port. The task of accommodating the media
channels will be handled by Stateful inspection's <span class=SpellE>fixup</span>.

Inspection (GPI), introduced in Cisco IOS Software Release 12.3(14)T, offered
complete integration with PAM. Prior to GPI, a firewall policy was defined
by configuring inspection for outbound TCP, UDP, and ICMP traffic. Inspection
was explicitly configured for specific protocols, such as FTP, H.323,
Skinny, Session Initiation Protocol (SIP) and others that required <span
class=SpellE>fixup</span> to watch for and allow protocol-specific media
channels. Common single-connection services such as POP, Telnet, Microsoft RPC,
and other simple protocols were inspected by the generic capability
of TCP, UDP, and ICMP inspection. Using these generic inspection capabilities
is simple to configure, but it limits Stateful Packet Inspection's
granularity-any traffic that was allowed to leave through a firewall was
allowed to return because inspection created an ACL Bypass entry for that
traffic.<o:p></o:p></span></font></p>
