A year or so ago after signing up for the local telco ADSL service I 
discovered I couldn't get any server to operate.  After some tests and 
investigation, I concluded that inbound was blocked on many if not all 
ports.  The telco's response to an email that related my findings confirmed 
this to be the case.  I've since dropped the telco service and am now with 
one of the smaller ISP's who's interest is much more service oriented than 
with just collecting the money.
