Hi Ryan,
Next step: run Wireshark and see what you see during the traceroutes.
Are they leaving with a reasonable TTL? Is it certain that nothing
returns? Are the packets going to the ethernet MAC address you expect
them to?
I had a fun problem once when I cloned some VMs but neglected to
change the source MAC address. They all seemed to work under light
load but get two downloading at once and suddenly they both
experienced major packet loss.
Regards,
Bill
