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
Definitely the direction I'm going. Even aside from the traceroutes, I'm going to capture some regular web traffic to see what is happening. Planning to send traffic to a machine I control to see if any packets are actually making it through at all. I'm not sure if this new Linksys router has any packet capture ability that is exposed to the end user, but I'd also love be able to see what's actually going through the router itself. Thanks, Ryan
