I have the below scenario...
I have a Cisco ASA firewall connected to Internet via public IP.
I have a URL published in the internet pointing to hte public IP
ex abc.test.com -> 184.108.40.206
In the ASA i have configured SSL VPN to send the request to my web server.
The ASA is configured to send the request to Web Server on port 5555
So whenever user browse the URL it hits the ASA & ASA sends the request to the Web server
The web server intern connects to the App Server . The communication between App & Web Server occurs on many ports.
When the Web server talks back to the Firewall what port should the Web server should use. Does it uses the port 5555 or any other port which is used between the Web & App server.
