QuantumGate::Access::Manager::AddIPSubnetLimit

Adds an IP subnet limit to the instance. An IP subnet limit can be used to set a limit on the number of connections that are allowed from a certain IP subnet. This can be used, for example, to prevent an attacker from flooding a peer with connections from a subnet that they control.

Signature

1. Result<> AddIPSubnetLimit(const IPAddress::Family af,
                             const String& cidr_lbits_str,
                             const Size max_con) noexcept;

2. Result<> AddIPSubnetLimit(const IPAddress::Family af,
                             const UInt8 cidr_lbits,
                             const Size max_con) noexcept;

Parameters

Name	Description
af	The address family for which to add the subnet limit. See QuantumGate::IPAddress::Family for more details.
cidr_lbits	The CIDR leading bits to use for the subnet, e.g. 24.
cidr_lbits_str	The CIDR leading bits to use for the subnet, e.g. /24.
max_con	The maximum number of allowed connections.

Return values

Returns a QuantumGate::Result object equal to one of the following QuantumGate::ResultCodes:

Value	Description
QuantumGate::ResultCode::Succeeded	The operation succeeded.
QuantumGate::ResultCode::Failed	The operation failed.
QuantumGate::ResultCode::InvalidArgument	The operation failed because an invalid argument was passed through.
