+## Abstract 
+We focus here on escaping NAT for the project P2PRC. The intial 
+plan is to use a middle server with an IPV4 address to escape NAT. 
+The future plan would be to use a WebRTC approach to where we 
+use a middle server to intansiate a direct p2p connection 
+using UDP sockets with nodes behind NAT. 
+
+## Archtecture plan 
+The server behind NAT would use a reverse proxy server with an IPV4 address 
+to be a possible way to communicate with the outside world. 
+
+Ex: 
+```
+        NAT
+         |
+Server  <--> Reverse Proxy server with <--> Clients 
+         |   public IPV4
+```
+
+We use the libaray known as [frp](https://github.com/fatedier/frp). 
+"frp is A fast reverse proxy to help you expose a local server behind a NAT 
+or firewall to the internet." 
+
+The server behind the NAT IPTable would be broadcasted through the reverse proxy.
+The mapping would be done automatically though P2PRC because the reverse proxy 
+could have certain ports already taken. 
+
+We are introducting a new concept of detecting reverse proxies over P2PRC. 
+We call this ``` reverse_proxy_server.json ``` and ``` reverse_proxy_mapping.json```. 
+
+This draft is still underway :)
