We recently switched from a Sonicwall NSA 4600 to a Cisco ASA 5508. We have a website located in our network that worked on all computers when we had our old firewall connected, now we have a few computers that are not able to access the website outside of the building. What is really strange is on the PC's that are having the issue, they can get to the site via IP address, also the affected computers are resolving DNS correctly. My computer is affected by this so I have been able to troubleshoot it like it was a PC issue but have been unable to find anything that would cause this. I am at a loss on how to correct this short of plugging the old firewall back in.
