PPP would be necessary if authentication, compression, et al. is required, but |
| 52 |
I think that in this case none of this is necessary, at least as far as the |
| 53 |
Linux PC is concerned. The incoming usb0 interface (or whatever the Android |
| 54 |
is recognised as) will be seen as an ethernet interface by the PC and good ol' |
| 55 |
NAT will forward it out via the PC's default NIC. I could be wrong, but |
| 56 |
without access to Helmut's phone I can't speak with any certainty. |
