Error in File Transfer Proxy

Hi all

I use Wildfire 3.0.1 Server on linux and PSI as Client Jabber. The problem is when the users are in the internet and want to transfer file to LAN.

In the server have the following variables:

xmpp.proxy.enabled=true

xmpp.proxy.externalip=IPpublic(200.x.x.x)

xmpp.proxy.port=7777

In the firewall I have allow the following ports 5223, 5222, 7777 at the IPpublic(200.x.x.x).

In the PSI client I set proxy.domain.com at the “Data Transfer Proxy” field.

The acavanna user sends a file to mcalva, the xml at the acavanna is:

Please help me!. The problem is the proxy. How to fix it?

Thanks in advanced
