Hey All,

Sorry to bother the list, but I'm noticing that I've got no connectivity
to Hurricane Electric through GBLX from my Qwest DSL.

In this case, I'm trying to get to tunnelbroker.net:

...

Testing out through the T1 which goes via twtelecom works fine, as does
from co-loc in Seattle which goes through Integra.

Don't suppose anyone else is noticing this as well?


Asymmetrical routing for the win.  Did a trace from HE's LG to the DSL:

core1.fmt1.he.net> traceroute 65.102.72.22 numeric

Tracing the route to IP node  from 1 to 30 hops

Since i'm taking two separate paths, I'm not sure where the problem is exactly.
