Cato Networks Knowledge Base

What is the Cato Network Rulebase

  • Updated

The network rules are an ordered rulebase that define the networking policy for the account. Once the traffic matches the criteria for that specific rule, then the actions are applied to the traffic. Rules that are listed after the matching rule are not applied to the traffic.

Note

Note: The Cato Cloud and Sockets don't support PIM protocol or multicast routing. To use multicast routing over the Cato Cloud, you need to establish point-to-point tunnels between the PIM routers using GRE (or equivalent) protocol.

For more about working with network rules for your account, see Configuring Network Rules.

Understanding Network Rules

The following settings define the match criteria for a network rule:

  • Type - WAN or Internet traffic)

  • Source - Cato Management Application entity (default is Any traffic)

  • Destination - Cato Management Application entity or Internet

  • App/Category - specific applications, categories, and other objects

  • Bandwidth - Bandwidth Management profile assigned to this rule (QoS)

Note

Note: When you configure Route/NAT settings for a rule, the rule must use Active TCP Acceleration. This feature is automatically enabled for the rule, and you can't disable it.

Overview of the Default Network Rulebase

Cato provides a set of network rules that are specifically tailored to provide the best user experience by prioritizing certain traffic over others. You can modify the default predefined network rules.

Cato's implicit network default rule is configured to perform TCP Proxy. As such, if no prior rule caught the traffic, TCP proxy is applied.

The following table explains the predefined network rules:

Rule Order

Rule name

Purpose

Priority

PBR

#1

WAN Voice & Video - Predefined

Prioritize voice and video traffic across the WAN.

P10

Transport - Primary: Cato, Secondary: Automatic

#2

Internet Voice & Video - Predefined

Prioritize voice and video traffic towards the Internet.

P10

Transport - Primary: Cato, Secondary: None

#3

WAN RDP - Predefined

Prioritize RDP traffic across the WAN.

P20

Transport - Primary: Cato, Secondary: Automatic

#4

Internet RDP - Predefined

Prioritize RDP traffic towards the Internet.

P20

Transport - Primary: Cato, Secondary: None

#5

WAN SMB - Predefined

Prioritize SMB traffic across the WAN.

P30

Transport - Primary: Cato, Secondary: Automatic

#6

Internet SMB - Predefined

Prioritize SMB traffic towards the Internet.

P30

Transport - Primary: Cato, Secondary: None

#7

WAN Data - Predefined

Prioritize data traffic across the WAN.

P40

Transport - Primary: Cato, Secondary: Automatic

#8

Internet Traffic - Predefined

Prioritize traffic towards the Internet.

Default

Transport - Primary: Cato, Secondary: None

For each rule, these are the PBR and Acceleration and Optimization settings:

  • NIC: Automatic

  • Route/NAT: None

  • Acceleration: Enabled

  • Packet Loss Mitigation: Disabled
