pg_hba.conf & putty

["Moritz Bayer" <moritz(dot)bayer(at)googlemail(dot)com>]

dear list,

I know there are already hunderts of posts about pg_hba.conf, but still after reading a few of them I still got troubles with this topic.

I've got a vpn server  with a ststic ip address, java apps are supposed to run there receiving data from a postgresql database.
The database is running, but for changes on it I want to open a putty connection while using pgAdmin.
In putty, I define a tunnel to port 5432, its displayed like this: Lserver.ip.address:5432

Thought this entries in my pg_hba.conf would do it:

# "local" is for Unix domain socket connections only
local   all         all                               md5

# IPv4 local connections:
host    all         all         
127.0.0.1/32          md5

# IPv6 local connections:
host    all         all         ::1/128               md5

well, it doesn't. When i run  pgAdmin with an open  putty connection, it still says: error connecting to server.

Any hints how I can find out whats still wrong?

Thanks in advance,
Mo
