I use microcontroller and want to connect GSM(PPPos) modem to PC(Ethernet)

to forward ipv4 packets first need a set connection. The PC sends an ARP
request and how to make it get an answer. Can I take bytes from the receive
buffer and encode them into the PPP packet? and after send to the GSM modem
PPP does not support ARP. You need your ethernet interface to provide
the ARP response (in the LwIP stack).
I believe to do IPv4 forwarding, each interface will need their own IP
address, and LwIP would need to have a route or two to route them?
