proxyBindAddr is only bind ALL proxy to particular IP address.
Could I bind proxy ssh/22 to 127.0.0.1 and http/80 to 0.0.0.0 in the same server ?

If I understand what you are requesting, you want to specify source address of frp server and client. It is possible, but only for TCP connections, UDP based connections do not work and you need to use a wrapper to call the frp client.
The setting to specify bind addres on frp client is ConnectServerLocalIP , you need to put it in general section of frpc config
transport.ConnectServerLocalIP = "IP_addr"

Also on the server there is a option bindAddr

remoteIP is not supported. Please use proxyBindAddr and multiple frps instances to achieve this kind of requirement.
