Well, yes and no. You could alter the source code to add the LSRR option when forwarding packets. You will find, however, that many systems out there in the Internet will not honor LSRR requests, with one of three possible actions: 1) Your packet is silently thrown away. 2) Your LSRR option is ignored and a message is logged to the gateway administrator. 3) Your packet makes it to the other end, which ignores LSRR options and so is unable to reply to you. -GAWollman -- Garrett A.
