client-source-address
Use this parameter to enable the MITM function on some devices only.
It's a list parameter using commas as the separator.
You may specify a single IP address or use a CIDR block. Both IPv4 and IPv6 are supported.
You may use the - prefix to exclude some clients, e.g., client-source-address = -192.168.1.2, 0.0.0.0/0
If the parameter is not set, MITM is enabled for all clients. A equivalent to client-source-address = 0.0.0.0/0, ::/0
127.0.0.1 should be included if you want to enable MITM for the current device.
