I am hoping to use easyeda in classroom tutorial i'm giving in two weeks. I plan to help the students learn to do manual PCB design, but want to also show them the autorouter. The challenge is that in this school, all external urls / ip addresses  and ports have to be whitelisted a head of time to allow them to be reached. he students are also not able to download software on their chrome books, so installing  the local autorouter is not an option. Does soemoen know the ip address(es) and ports used for the autorouter ?   Thanks !
