MQTT Connection through proxy possible? #616

Open t0m82 opened 5 years ago

t0m82 commented 5 years ago

I'm using the PubSubClient to connect to our IoT Platform via MQTT and everything is working fine. I'm working with an ESP8266 NodeMCU as hardware, ESP WiFi Lib to connect to the internet. Now I try to implement that client in our corporate network and there I'm facing to deal with a proxy ( 123.123.123.123:9400 ).

Is it possible to connect through a proxy with the pubsubclient? Or no chance?

There is nothing in PubSubClient that deals with proxies. It leaves all responsibility for creating the network connection to whatever Client object you give it. I am not aware of a suitable Client that can work with proxies - but it isn't something I've ever had to research, so it may be possible.

Ah ok. so it is the job during the network/Wifi connection to deal with the proxy. The ESP Wifi Lib offers just the possibility to work with gateways (IP only), not with a proxy and certainly not with a proxy IP and port... any hint where to start with research..? Any idea?
