We have an additional interface that goes off to another company via a leased line.
When web protection (transparent) is enabled, we can reach their server on port 80. When we disable the web proxy, we can't reach their server. We have added FW rules to allow this and can see in the logs, traffic going to the server on port 80 and the server replying on port 80. But we can't get to it via our browser unless the web proxy is on.
There are no settings in the browser and all other traffic looks ok. We've also tried this on another port 22222 and it's the same. We can't access the server even though the FW logs are clearly showing it go through.
There is no nat rules here and traffic is purely routed. We know the connection works as we have sip trunks and rtp going across the link without issue.
