Don't know if it is related, but we can't route email to bellsouth.net -- no


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
