You have to have an ACIA/Swiftlink RS-232 interface for the C64 and connect 
this to the serial port of a PC. Configure the PC to forward IP packets and 
run the SLIP protocol over the serial line. If the C64 should have an IP 
address in the same subnet as the PC, the PC will have to act as an ARP proxy 
for the C64 as well.

I have not actually tried this with a real C64 since I don't own an RS232 
interface, but lwIP has been run on other systems using the principle above. 
The C64 port of lwIP has been run in the Vice emulator, which has RS232 
interface emulation.
