hello reply error 500 message

Hi all.
i'm getting a hello reply error 500 (invalid handshake) when i try to connect to gnet.
I think it's a firewall problem (suse 8.2) but i've mapped the 6346 port .
I take a lot of time to connect to gnet, when i do (sometimes even 2 hours).
my conncection is a 56 k modem( the same i used to run in win with the gnucleus and was ok9
But now i see that message comes from hosts running Bear Share .
any idea?

i reply myself.
seemed to be something with the hosts cache.
i cleared it, and down the number of hosts(from 24000 to 10000) and now it takes less time in getting connected with other gnet hosts.
