(Alternatively, the - router is sending the ICMP packet correctly, but the - firewall at the WWW site is dropping it.) When the www - server is sending you frames that do not fit into the PPPoE - pipe the Telco router drops them on the floor and your page - does not load (some pages/graphics do as they are smaller - than a MSS).
