I have 2 PCs behind a router (with forwarded ports), Connection=>Ignore local/private IP addresses option unchecked, and I couldn't transfer files between them. I tried to manually add a source (tried both with external and internal (192.168.x.x) IPs) but "Add Source" is a bit overcomplicated: in eMule you just type "address:port", but in Shareaza you need to type: "http://address:port/". After adding "http://address:port/" Shareaza displayed "Sources: 1", and didn't started downloading; to start file transfer I needed to type: "http://address:port/uri-res/N2R?urn:HASH".
Why Shareaza doesn't show dropped sources in download list?
Are default settings from Shareaza wizard suitable for internet connections of the year 2014? 4 torrents at once, 40 BitTorrent client connections, 35 eD2k clients (I'm not sure if these limits are per file or per program). When I share 2000 files (LeafOnlyMode) are 2 G2 and 3 G1 hubs sufficient? Maybe you should copy some tweaks of PeerProject client into Shareaza?
