About default in-path rules
Three types of default in-path rules ship with Edges. 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 appliances. The default rules allow the following traffic to pass through the appliance 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 (SteelCentral Controller for SteelHead Mobile). 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.
You review, add, edit, and remove in-path rules under Optimization > Network Services: In-Path Rules. The In-Path Rules table lists the order and properties of the rules set for the running configuration.
Configure the rules. The default rule, Auto, which optimizes all remaining traffic that has not been selected by another rule, cannot be removed and is always listed last. The default rule maps to all IPv4 and IPv6 addresses (All-IP:*). The default rule for TCP traffic, either IPv4 or IPv6, attempts autodiscovery with correct addressing as the WAN visibility mode.
