There is a big difference in the semantic of the address attribute: * tcpclient: address is the IP address to connect to. This could be on any machine, as long as it is reachable * tcpserver: address is the local IP address the agent binds to. This address must be configured on a accessible local interface, local process must have permission to open that server port
So if “because no ports on VM where PCF container is running is not allowed” is correct, you cannot use tcpserver on PCF. Regards, -marc > On 14.
