If I enable my firewall (and thus have Outgoing connections only), I get 30 to 150 results on a given query. If I disable my firewall (and thus have Incoming connections only), I get only 1-10 results on the same query.
I have tried at different times, different days... always the same phenomenon.
Is that normal ? Is there a solution ?

I still have that problem with 0.7.1
Am I the only one ?

If I remember correctly an old Version of Fury (the predecessor of Phex) had three network options:
# minimum connections
# maximum connections
and
but not more than # incoming.
Reactivating this feature in Phex should solve your problem.

Thanks. Let's hope it can be re-implemented in the next release.
