Receive and pass data from remote http post to meteor react client

Hi guys,

I am setting up a smart captive portal using meteor for the purpose of updating our database.i am using a mikrotik router for that.i learnt that the router wont be able to host the client app but i LL be able to redirect every request made to a remote server hosting my meteor app .the router will post via http some data to my app(IP,mac adress)…so my question is how do i catch the posted data from my router to use in my react client? I thought of using meteor simple rest but i am not sure.please help me
