This disclosure is directed to techniques for providing communication between devices in different networks wherein the communication must first pass through an encryption mechanism and the devices do not have the stand-alone capability to encrypt or decrypt the communication. According to these techniques, an adapter may determine certain fields in a data packet that remain unencrypted when the data packet passes through the encryption mechanism. The adapter may then process those fields in such a way that, when the data packets are received by a second adapter, the second adapter may read those fields and obtain information.
