Hello Cisco Experts,
I have recently been assigned firewall duties at work. I'm not terribly good with the cli yet (but I'm working on it) so I tend to do configurations using the ASDM utility. We have a user that is testing some stuff on our web site. He is using www.crossbrowsertesting.com
. I have looked up the error that he gets when he uses their site and they state I may need to open some ports on our firewall.
Add a rule to your firewall allowing connections initiated from inside your firewall on either port 80 and / or ports 6020-6100 going to 220.127.116.11 (crossbrowsertesting.com) to be completed successfully.
Can one of you Cisco experts tell me how to open the ports 6020-6100 using the ASDM or am I better off doing this with the cli?
