9.4.6. IPsec Advanced Settings
The following cOS Core advanced settings are available for configuring IPsec tunnels.
IPsec Max Rules
This specifies the total number of IP rules that can be connected to IPsec tunnels. By default, this
is initially approximately 4 times the licensed IPsecMaxTunnels and system memory for this is
allocated at startup. By reducing the number of rules, memory requirements can be reduced but
making this change is not recommended.
IPsec Max Rules will always be reset automatically to be approximately 4 times IPsec Max
Tunnels if the latter is changed. This linkage is broken once IPsec Max Rules is altered manually
so that subsequent changes to IPsec Max Tunnels will not cause an automatic change in IPsec
Max Rules.
