IPSectarianism

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...

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?

Cheers
Dave
