Which ports are blocked?

[Ryno]

Hi guys,

I’ve just recently signed up for my iburst UTD, so I’m still trying to gather all the bits and pieces about their product. When I collected my UTD they gave me an invoice, a CD (with pretty useless documentation and non on linux…) and the UTD itself. So much for client services… Anyway, I’ve saw a couple of post by various people speculating about iburst blocking all inbound traffic to port 25 for SMTP. Does anybody know which are indeed blocked and which aren’t?

Thanks,

R

NONE are blocked actually, SMTP is merely 'filtered', you could apply to have your server added to the list of allowed servers, it was their attempt at stopping spam (not realising I could run a SMTP server on any port to relay spam I guess)

No protocols or ports are blocked and SMTP is the only one filtered. They do packet shape certain protocols and throttle all protocols other than priority ones. Multithread works on all ports though so you can get full speed on almost anything on any protocol. Not p2p though, you need to work arounds to get full speed on that.

Hi,

what are the work arounds? If they've been posted somewhere else (and it's a mission to repeat), let me know and I'll try search. Just saw this and thought I'd ask.

thanks.

Actually only OUTGOING traffic on port 25(tcp) is dropped. ie. UTD-->Internet

Incomming traffic on port 25 (ie host your own mail server) is quite possible.

the workaround is just to host a smtp server on your machine and change the port.. but whats the point

work arounds

Hi,

I meant for P2P... Like the dreaded kazaa... It was shockingly slow when I tried it and when I read this post, thought this might be why.

Thanks.

hate to sound like an ass, but Ive covered this extensivly and if you can do an advanced search you can find one of the looooong posts I did about it. What you are looking for is methods around packet shaping not port blocking, if you read the posts and need help PM me

thanks. That's exactly what i was looking for. I thought you might have covered this.
