Hi there,
I would like to work with you to troubleshoot and fix this ASA firewall for you.
I have been working on Cisco ASA firewalls for 11 years. I have worked with ISPs installing, configuring and troubleshooting Cisco ASA and other firewalls (SRX, Checkpoint, Palo Alto and Fortigate).
If you have any questions or want to have a quick chat with me, please don't hesitate to contact me.
Kind Regards,
Shahzad
