Application connection Issue

[saquib.tandel]

Hi

Financial module service is outsourced in the organization
Customized application installed on LAN workstation needs port 9090,9091,9092 to be opened to reach
Financial Module Server hosted on Internet.

FMS_Server----{Internet}------((R))----Firewall----((Core))------LAN

                                                                                   |||

                                                                                Proxy

Default_Gateway for Core is Firewall
Users default_Gateway is Core

Users IE is configured with Proxy_Server

Application doesnt uses IE settings ( no option in application to put proxy )

Firewall got ACL_Inside and ACL_Outside

On ACL_inside all IP is allowed to communicate with port 9090,9091,9092  but Application cannot connect to the
Server hosted on Internet.

It only works when I  do a static NAT with Public IP

Any Help

Hi,

When you are travelling from Higher to lower security level you need to have NAT enabled. It could be Static NAT or PAT.

Hi

When someone from outside needs to reach inside he too needs a NAT

( example is publishing a website )

if above is true then whts the difference.

How can I make it work with PAT

( If I got a DSL connection then the Financial Module application connects like a champion, DSL is without regular static IP )
