Connection refused (0x0000274D/10061)

Good morning to everybody

I have a pg9 db to wich i can connect to by local but not from remote. In the properties of the postgres db , the port is set to 5300 (not the default 5432).
I tried to connect in remote with pgadmin3 and quantum gis, both give the error Connection refused (0x0000274D/10061).
This is the complet message in quantum gis (but is silimar in pgadmin3)

"could not connect to server: Connection refused (0x0000274D/10061)

Is the server running on host "95.110.201.74" and accepting

TCP/IP connections on port 5300?"

Whit both the programs installed on the same pc of the db, i can connect without problem to the db.

I already did these settings:

- in postgresql.conf : listen_addresses = '*' and port = 5300 (in the place of the default 5432)

- in pg_hba.conf:

host [dbname] all 0.0.0.0/0 md5

host [dbname] all 127.0.0.1/32 md5

- restarted postgres

I also tried to substitute on the db properties "host=localhost" with "host=95.110.201.74"

On the machines are not active firewalls.

Have you any clue of what's wrong?

Grazie

Thanks
