SSH socks proxy server on by default

I need some help with SOCKS proxy server based on SSH. I am running SSH SOCKS proxy using this command: ssh -N -D 0.0.0.0:1080 localhost Can I somehow enable it by default? The ssh deamon is on by default anyways, so there must be a way to configure it. Also, I am using 0.0.0.0 to allow all incomming ip addresses. Can I limit it to a subnet? For example 192.168.1.0/24. Or maybe at least an interface name.
