OK, but is NATing configured the same way for both Linux & MS Windows |
11 |
machines? |

Does your router give you the option to log outgoing packets, or monitor them |
18 |
in real time? |

That's how it should be if you want your Linux box to respond to pings. |

Can you ping the IP address of ftp.ucsb.edu; i.e. 128.111.24.43 (although I |
40 |
would expect that if your linux had DSN problems you wouldn't be able to |
41 |
browse from it altogether. |
