Don't know if it is related, but we can't route email to bellsouth.net -- no route to host. When I checked it rattles around inside their network (assuming traceroute is trustworthy). Their customer support (first number I found) report they have a ticket already open. They know they have a problem, but didn't supply any details, I didn't ask. I just wanted to know it wasn't specific to our own address space, and they knew they had a problem, it isn't, they do.

Hi, Thanks for replying, it doesnt seem to be related based on the traceroute you provided. I am still seeing the issue this morning, but its not so wide spread across protocols. I worked around the issue by dumping out my traffic to them via Teleglobe instead of MTSAllstream. Teleglobe seems to talk to them on a different router in Chicago which doesnt seem to be showing the behaviour as much as the other router or at least its not on the source IP addresses I am using. However, its stil blocking IPSEC packets I got an email from the datacenter early this AM saying the problem was fixed according to UUnet, but it still there when I just tried now. Is this the result of some protocol prioritizing config gone bad ? Or busted software ? e.g as of this morning, icmp,tcp, and udp packets make it to the other side but not IPSEC traceroute -s 67.43.129.246 -Pudp 209.167.35 traceroute to 209.167.35.xx (209.167.35.xx)
