I am currently having issues getting a google wave in a box working. I can currently get my server to run and I can access it using lynx when I am on the machine. Although I can't access it externally. When seems to only allow me to access the server using the settings which comes from the "http_frontend_addresses" property. Below is my config.
<property name="wave_server_domain" value="<public dns>" /> <property name="http_frontend_public_address" value="<public dns>:9898" /> <property name="http_frontend_addresses" value="<private ec2 ip>:9898, localhost:9898" />
