tip: in the future, i suggest sending a new email for a new topic.
it will both have a better eye catching subject, and will also not hide 
inside the GPFS thread which the networks folks may be less interested in.

that's an interesting use case, i don't think we encountered same vlan 
number in separate physical networks in same data center.
just wondering, any reason the vlan number is identical between internal 
and external networks (i mean, it is obviously not really the same vlan, 
as these are physically separate networks)?
