How to speak through firewall?


We installed speakfreely. However I can here other guy and he cannot here me. I think that this is due to his firewall. He cannot remove firewall because it is installed by internet provider. They (provider) told him that they support only TCP protocol.

How can we speak through firewall?

Tanks in advance for all who can help me.

What sort of firewall only supports TCP? I think that you need to put a little pressure on this ISP to allow UDP packets through as well (although it would help if you could be specific about the particular ports that need openeing up)

Thanks

Thanks of course. It is a good advise to press on ISP. Perhaps it is the best solution. However we pressed on ISP. It did not help us. (They are in Russia.) Therefore I think that now remains only more hard way - to find how to speak through firewall.

In Europe all ISP's have to set all ports wide open. They may block ports for there servers but not internet connections from homes or bussiness if it isn't requested!

Thanks for information. However it does not help. Only little part of Russia is in Europe.
They (ISP) tell that they do not yet afford this service: UDP protocol. May be later they will.
Though I do not understand, why there are difficulties with USB.

You could always do a little bit of Firewall Tunnelling...

http://www.linux.org/docs/ldp/howto/...ing/index.html

UDP ports 53 & 63 for dns and whois are open.
Make a tunnel between each machine on one of those ports and send your speech programme through that.

Regards,
Peter
