Re: ISP blocking packets with protocol 41 ?

ISP problems (or their uplink!)

You should take it up with Infostrada. They probably are not selling you
unfiltered IP access.

It's most probably not them blocking proto-41 traffic inbound. The ISP
I was a (satisfied!) customer at in Belgium (Telenet) blocks all sorts
of incoming traffic (ie, they block everything except tcp/udp/icmp/igmp
proto). I could not tunnel IPIP, IPv6IP, GRE, and could not connect inbound
to ports TCP < 1024.
You could request unfiltered access, or move to another ISP. At SixXS
(http://www.sixxs.net/) we have several italian users. I know of at least
one who's upstream was blocking proto41 (amongst others).
