RE: Comcast and IPSec traffic

["Clark, Steve" <Steve () clarksupport com>]

I had a nice conversation with Comcast after starting to block 135 some
weeks ago and found the only difference between their standard service and
the Pro service is the 5 "persistent" (note: not static) addressed. They do
not block IPSec traffic on the standard service and are using the "VPN
compatible" line as a sales tool.

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.
