Hi, sorry, but I don't understand what you mean with stream {}, my nginx config for the RD Gateway is the following:

server {listen *:6080; listen *:6443 ssl;
server_name ~^rdg..*$; include ssl_rdg.conf;
location / {proxy_pass https://s2012-rdg; include proxy_defaults.conf;}}

Should I replace proxy_pass to stream?

Regards,
Fred
