We have a Cisco ASA 5505. As of yesterday we could no longer access our web server (the web server is hosted off-site). Pinging the DNS address and direct IP (from the firewall and a PC) both return no response. Pinging the IP from the T1 router responds properly, meaning the router can access the web server, but the firewall cannot. Accessing the web server has never been a problem, and no configuration changes have been made to the network/firewall. Other locations can access the web server just fine.
I don't have experience with Cisco firewalls, but I do have access to it via ASDM. Where do I start? What should I do? Any help is appreciated.
