Like it was written in that page (the URL you gave), ARP is not suited
for access-control when the connection comes from beyond your
subnet. 

Isn't lwip_getpeername() more suited? After the lwip_accept() gives
you a new socket for the connection, examine the address with 
lwip_getpeername() and drop the connection at your will.

I think so. Unless you hack the lwIP core API yourself.
