Setup firebird via internet

I have read threads about this case in this forum and follow the instruction there. But, I still cant connect to firebird via internet.

I set my router 'virtual server' :
Protocol = TCP,UDP
Port start = 3051
Port End = 3051
Port Map = 3051
Port Map End = 3051
uPnP enabled , PVC0

I tried to scan the port using Open Port Scanner
After I press 'check' on the web, my firewall start, asking me to gives access for incoming connection to firebird, the I press "Yes"
the web says, the port is open.

but when I try to connect using tibdatabase
databasename = 123.123.1.121/3051:AliasDbase
it cant connect. with error msg:
unable to complete network request to host '123.123.1.121'
failed to establish connection
no connection coul be made because the target machine actively refuse it


Can anybody give me any pointers?

did you configure Firebird to listen on port 3051? The default port is 3050. You might need to insert this port in the services file /windows/system32/driver/etc/services on windows or /etc/services on linux

is firebird installed on the server? first try to connect from a computer in the LAN, and if you're okay, then try from the internet.

for me it seems like it's a network configuration problem.

It works just fine if I connect to LAN.
localhost/3051

Do you have a static public IP address? On dynamic address you'll have problems.

It is a public IP address. But it's dynamic, so every time I reset the modem, the IP change.
But when I am trying to connect to Firebird, I check my IP first, then try to connect to that address.

Do I had to have a static IP?

Yes i had the same problem yesterday setting up a webserver for a company.
Then i called the provider and asked for a static IP, and the problem was solved.


When you have a dynamic address you can use Internet, but one from Internet cannot find you because there is no public route to your address, only inside your ISPs network.

Ic, Thanks..
I need to ask for static IP then
