[lwip-users] lwip PPPoS + ESP8266 wifi module

Hi everyone,
I'm using lwip on the ESP8266 wifi module.
This module is connected to my card and communicates via PPPos (the PPP client is the Wifi module).
Now I need to receive and transmit TCP and UDP packets via Wifi.
Initially I created two TCP sockets (netconn), one client and the other server forwarding the data via buffers, but it is very expensive in time and memory.
I have doubts about this implementation considering that I will have to do the same with the UDP transmission.
Board( --> PPPoS --> netconn TCP client( --> netconn TCP server( --> mobile system (
I thought of using the network interfaces (netif, one the PPPoS and the other the WiFi) to do a kind of forwarding...
could this be the right way? Can the UDP part coexist?
Do you have any suggestions?
Thanks in advance
