A while back, Cox @Home made it very clear that the use of VPN protocols is prohibited. AT&T @Home (my provider) hasn't made any similar statements, so I think it's more of a policy issue for the various cable companies than it is for @Home themselves. Of course, there's always httptunnel. Stick your IPSec/PPTP/L2TP traffic inside good old http and you'll get anywhere you need to go... _______________________________________________________ Steve Riley Microsoft Communications Consulting in Denver, Colorado steriley@microsoft.com +1 303 521-4129 (OLD mobile) www.microsoft.com/isn/ Applying computer technology is simply finding the right wrench to pound in the correct screw. -----Original Message----- From: Dave Wardle, Critical Networks, Inc. [mailto:dave@criticalnets.com] Sent: Tuesday, January 16, 2001 7:49 PM To: nanog@merit.edu Subject: IPSectarianism Back in November 2000 I read with interest a thread discussing the implications of Service Providers blocking particular protocols (I believe it was "Operational impact of blocking SMB/Netbios"). I recall one response which explicitly stated that IPsec was not blocked. Is anyone on the list aware of Service Providers (ISP/NSP...) who DO block IPsec traffic, with or without informing their customers or peers? I'm trying to assess the pros and cons of major Enterprise Customers basing their entire remote office/small office/mobile network access strategy on some type of IPsec based VPN solution. Any thoughts?
