Update, noticed that when i disbale transparet proxy more saits work but not all. For example https://google.se works but not https://google.com giving me as many other saits TTL CA error.
Today I also tryed to reach my internal rescourses on https but then i get the same error. This is with load balaning off and no proxy.
My setup is: client has ZS as gateway, ZS has Another router as gateway in the same subnet. Have portforward/NAT on upsteam gateway pointing directly to my internal resource. Is it the same error both ways that im jumping between gateways on the same subnet?
