 ## 1. DNS and TLS
 
 Create `tapm.scity.us` in PowerDNS and point it at the existing HAProxy
 frontend. Install the certificate using the existing certificate automation.
-The broker only listens on `127.0.0.1:8080`; Nginx terminates TLS.
+Set `TAPM_LISTEN_ADDR` to each node's physical address when the load balancer
+connects directly to port 8080:
+
+- Webserver-Node1: `10.10.1.121:8080`
+- Webserver-Node2: `10.10.1.122:8080`
+
+Restrict port 8080 to the load-balancer addresses. If Nginx terminates TLS on
+each webserver instead, keep the broker on `127.0.0.1:8080`.
