pgadmin tunnel problem

Hi,

I have a couple of postgresql servers running and they work great with 
putty and ssh tunneling combined with pgadmin. I have one problem server 
though and I am looking for help.
My public IP is firewalled, and I port forward port 5432. My server IP 
at 192.168.100.18 works fine with code residing on the server itself, 
connecting via localhost.

My pg_hba.conf contains the following setup:

local   all     all                                                     md5
host    all     all             127.0.0.1       255.255.255.255         md5
host    all     all             192.168.100.18  255.255.255.255         md5
host    all     all             66.66.66.66   255.255.255.255         md5
host    all     all             77.77.77.77   255.255.255.255         md5


Where 66.66.66.66 is my local public IP and 77.77.77.77 is my public IP 
for the firewall and hence the server.
Usually I setup my putty connection to tunnel a port like 35432 to the 
public IP of the postgresql server, say 77.77.77.77:5432
And in pgadmin I connect to localhost on port 35432 and all is well, 
when I do not have a firewall in the chain...

In my case with the firewall, even with port forwarding setup for port 
5432, pgAdmin times out after 5 minutes or so complaining about SSL 
handshake not working...
I have installed a server.crt and server.key file in the pgsql/data 
directory and the server seems to work fine with ssl_enabled in the 
postgresql.conf file, and tcp enabled.

What might be causing pgAdmin these connection problems... I am not sure 
if the firewall is the culprit or if I screwed up something with SSL...

Any insight most appreciated...
