Is AT&T Excite at Home blocking IPSec port

[Falkovich, Alex -LNL-]

We have had a remote access in place where broadband users would
authenticate to our Domain using CISCO VPN 3000 client and then access a
Citrix Metaframe server on the back-end. In essence, they would be running
the Citix's ICA protocol on top of the IPsec. This set up worked OK until
yesterday; - all of a sudden, none of the folks who were using AT&T cable
modems could access the Citrix server. In fact, they would not even get the
login screen, although they could ping it OK. I was wondering if AT&T has
finally delivered on their promise to block the IPSec port? Does anybody
know?

thanks.
