Each proxy thread has a register (SEC_PROXY_THREAD[a]_CTL) to define the direction for access. It can either be an outbound proxy thread for writing messages to resources. Or it can be an inbound proxy thread for reading messages from resources. The host must match the direction programmed or it will result in a proxy thread error.
