italian provider screwed

well since the last 2 minipatch we cant play with each other

i know 4 5 guys playing demigod all with the same provider we all have 4 MB-20MB connection and we ping each other like 50

i play very well since day 1, we did play a lot of game and apart from the game being a bit slow there was no probl

now as i said since the last 2 patches we cant connect to each other, if i host a game my friend cant join it, if we both join a game hosted by someone else 90% of times we connect each other in a second BUT we get ping 0 and so the game doesnt start

i repeat in the connection status we are perfect, all connected in a second but cant enter in each other game

our provider works like a big lan between us, we dont have a static IP and so on

the situation in the last days has been critical, we could hardly play some game and it was PERFECT 1 week ago
