Just a general question looking for suggestions. We have had some minor issues with accessing websites externally. We use a cisco firewall that has been in place for about 5 years. What will happen is non-NAT machines will not be able to access a certain website through the firewall it comes back unavailable. Machines that are NAT addressed will access this site fine and the same non-NAT machines have no issues on other networks. This only happens for maybe one out of 10000 websites we try to access. I have no clue what it could be or even if it is on our side. I am looking for suggestions as to where to start.
