hi arne,
thanks for the reply. infact in the phex svn i could find much more documents that are not there in gnutella's org site and unreachable through google.

but the answer to my question still remains open , the document at
has a line like this
:
This Push Proxy proposal outlines a technique to do away with these problems,
35 therefore increasing the likelihood that a downloader can get content from a
36 firewalled server. This proposal does not address the problem of a firewalled
37 downloader attempting to get content from a firewalled server.


the line is quoted in :
SourceForge.net Repository - [phex] View of /phex/trunk/docs/Gnutella/proposals/Push Proxy 0.7.txt


firewalled servents are very common these days and it is almost always the case that both the servents would be behind the firewall. how is phex handling this ? there are workarounds for that and i am really surprised to see none of the gnutella clients mentions it in their website for it.
thanks
