one or more hardware processors, configured to:
receive, from a client network device, a first control message that includes a control enablement parameter and a server identifier parameter that indicates an Internet protocol (IP) address of a server network device;
receive, from the client network device and after receiving the first control message, a first message that indicates a first source IP address as being an IP address of the client network device, a first destination IP address as being an IP address of the pluggable transceiver, a first source port as being a port of the client network device, and a first destination port as being a port of the pluggable transceiver;
update the first message to indicate the first source IP address as being the IP address of the pluggable transceiver, the first destination IP address as being the IP address of the server network device, and the first destination port as being a port of the server network device;
send, to the server network device, the updated first message;
receive, from the server network device and after receiving the first control message, a second message that indicates a second source IP address as being an IP address of the server network device, a second destination IP address as being the IP address of the pluggable transceiver, a second source port as being a port of the server network device, and a second destination port as being the port of the client network device;
update the second message to indicate the second source IP address as being the IP address of the pluggable transceiver, the second destination IP address as being the IP address of the client network device, and the second source port as being the port of the pluggable transceiver; and
