Java Application to internet

[munawar.zeeshan]

I have a Java Application that connect to some server over the internet. After i installed PIX 501 on my network i am unable to connect my application to its server.Without pix its works great.

In local computer log i can see the application connecting on

static.1.1.1.1.clients.your-server.de:https

( 1.1.1.1 is the ip of the server that i have changed)

Any idea ?

Hi ..

Well first of all you need to find out which ports and which IP address that application needs to communicate with. Once you have those details .. it is just a matter of allowing that access on the PIX and you also need to create a PAT translation for the internal host to make it routable on the Internet.

For example let's say that your internal host is 10.10.10.10; the public server is 203.203.203.203 and the port that the internal host needs to communicate is tcp/6200 .. then you will need:

1.- create an access-list to allow this access

access-list Inside-Out permit tcp host 10.10.10.10 host 203.203.203.203 eq 6200

2.- Apply that access-list to the inside interface of your firewall.

access-group Inside-Out in interface inside

3.- Create a PAT to allow the host to be routable on the Internet

global (inside) 1 interface

nat (inside) 1 access-list Inside-Out

The above is just an example for your reference.

I hope it helps .. please rate helpful posts !!!
