I live in Los Angeles, and I'm experiencing very odd connect problems.

I have both a Cingular Laptop connect card, and a Cingular 8525.
Mostly i'm on edge, sometimes 3g/hsdpa. From anywhere in the world i
can ping 66.102.136.161 except on my cingular network. Sometimes it
works and most of the time it doesn't. It seems I can't access
anything on the 66.102.128.0/20.

From what i can tell of traceroutes, its not making it past cingular's
filters or firewall.

Tracing route to 66.102.136.161 over a maximum of 30 hops:

 1   332 ms   238 ms   239 ms  172.26.248.2
 2   819 ms   340 ms   617 ms  172.26.248.2
 3     *        *        *     Request timed out.

Anyone work for cingular or WDSPCo?

Other networks to the same provider work just fine. I know its not
filtering on the destination network.

Anyone else have the same problem?

Thanks

Andrew
