Default in-path rules

Three types of default in-path rules ship with SteelHeads. These default rules pass through certain types of traffic unoptimized. The primary reason that these types of traffic are passed through is because you are likely to use these types of protocols (telnet, SSH, HTTPS) when you deploy and configure your SteelHeads. The default rules allow the following traffic to pass through the SteelHead without attempting optimization:

Port type	Description and ports
Interactive traffic	Ports 7, 23, 37, 107, 179, 513, 514, 1494, 2598, 3389, 5631, 5900-5903, 6000. This default rule automatically passes traffic through on interactive ports (for example, Telnet, TCP ECHO, remote logging, and shell).
Riverbed Protocols	Ports 7744 (RiOS data store synchronization), 7800-7801 (in-path), 7810 (out-of-path), 7820 (failover), 7850 (connection forwarding), 7860 (SteelHead Interceptor), 7870 (Client Accelerator Controller). This default rule automatically passes traffic through on ports used by the system.
Secure, encrypted traffic	Ports 22, 443, 465, 563, 585, 614, 636, 902, 989, 990, 992, 993, 995, 1701, 1723, 3713. This default rule automatically passes traffic through on commonly secure ports (for example, SSH, HTTPS, and SMTPS).

We recommend you retain the default rules. However, you can remove or overwrite the default in-path rules by altering or adding other rules to the in-path rule list, or by changing the port groups that are used.
