maybe a bit OT, but a general question/gripe about cable ISPs...it seems to me they have a monopoly on their respective service area's, so what is to stop them from implementing the 'super-pro' service as the only option allowing IPSec but costly $XXX more...there is presumably some restriction in place or wouldn't they be doing this already? Understood that they must compete with DSL in areas where that is available, but I would guess that in the majority of their service areas there is not an alternate high-speed ISP. It seems I would have little recourse but reverting to dial-up if they decided to double my fee...

They do not block IPSec traffic on the standard service and are using the "VPN compatible" line as a sales tool. regards, Steve Clark Clark Systems Support, LLC AVI-EWS Charter Member "Who's watching your network?" www.clarksupport.com -----Original Message----- From: Greg Holl [mailto:gholl () tp devry edu] Sent: Saturday, September 13, 2003 5:19 PM To: 'security-basics () securityfocus com' Cc: 'mmcconnell () ctiusa com' Subject: Comcast and IPSec traffic Hi all, This goes back to a fairly old thread (8/13, not that old). Mark, you sent an email asking if anyone had noticed Comcast blocking IPSec traffic. Well, guess what Comcast has started advertising. Comcast is now offering "High-Speed Internet Pro" service. It offers and "even faster connection." And among other things, they list "VPN Compatible" on their benefits. I guess that answers your question about whether they are blocking IPSec traffic. -Greg
