Steven:
Can you collect a more detailed trace showing the ICMP requests and responses, perhaps using tcpdump to a file? There are some things I would like to check in the outgoing ICMP echo requests:
- IP TOS - IP header checksum - ICMP checksum etc.
These are things in the echo request where a misstep would lead to no response. I would also recommend grep'ing InterMapper's debug log for "ICMP" to check if any API errors have been logged.
Thanks,
