No USB ports here... neither on the modem nor the computer. > To actually get the second PC on the internet, your Linux PC will need > to have the following enabled in the kernel: > > Networking options ---> > IP: Netfilter Configuration ---> > Connection tracking [M] > IP tables support [M] > Full NAT [M] > MASQUERADE target support [M] Can't see those.
