I thought of this the other day and I thought I would share it: Question: Your PC is unable to traceroute to a server on the other end of the network. Between your PC and the server are two routers, R1 and R2. R2 has implemented a firewall which is denying ICMP echo requests and allowing all other traffic. You may not change the firewall settings. What is the solution to this problem? Answer: Stop using windows : ) Explanation: Most OS' use UDP in their implementation of traceroute, while Microsoft continues to use the ICMP echo-request packet. -- Regards, Joe Astorino CCIE #24347 (R&S) Sr. Technical Instructor - IPexpert Mailto: [email protected] Telephone: +1.810.326.1444 Live Assistance, Please visit: www.ipexpert.com/chat eFax: +1.810.454.0130 IPexpert is a premier provider of Classroom and Self-Study Cisco CCNA (R&S, Voice & Security), CCNP, CCVP, CCSP and CCIE (R&S, Voice, Security & Service Provider) Certification Training with locations throughout the United States, Europe and Australia.
