     11Please note that like the risky experiment facility that it extends, '''you cannot use ping (icmp) to verify that the access is functioning'''.
     12
     13The system gives specific access with different port sets to TCP and UDP and does not support ICMP at all.

    11 If you have an an existing experiment, and you want to grant it external    access, you can do so , even if it is already swapped in, without restarting the experiment.

     99For any experiment having a tb-allow-external call in the ns file (even with no parameters), a swap-modify will '''overrule''' any changes
