connectivity issues between ATTWS and 207.188.0.0/19

[phiber at phiber.org (Christopher Rogers)]

Hi all, we are having some issues with users attempting to reach our
public netblocks via ATTWS.  Our advertised ranges appear to be
completely unreachable from their wireless network.  The
route-server.ip.att.net verifies our netblocks are seen and reachable,
but this probably has something to do with the cingular network
infrastructure.  Connections via other providers- tmo, etc, all work
fine.

We are attempting to contact attws for support, but aren't making it
beyond the 'is your ipsec client configured properly?'  Could a
clueful engineer please contact me off-list at their earliest
convenience?

Thanks kindly
Chris
