File transfer cancelled

Hi I am using spark 1.1.4 and wildfire 2.5.1 because I am behind a firewall and want to transfer files with clientes that are out side my net. Hi have de wildfire server behind de firewall so I opened ports 5222 5223 and 7777, the wildfire server is my proxy server.

But when I send a file to a client outside my local net or when they try to send me a file, after one or two minutes I recieve the error file transfer cancelled.

I read at the jivesoftware portal that with spark 1.1 Users should never have to worry about how their network is setup or firewall .

I don´t know what I’'m doing wrong, any help?

Thank you

Luis

xmpp.proxy.externalip should be set to the external address of your server, the address that users connect to via the internet.

Cheers,
