I'm hoping someone could offer help how to solve a problem with having trying to access an R80.10 management server's private address behind R80.10 firewall with GUI client and failing. The setup is in Azure but I don't think that's the problem here since you can login via SSH to the server and HTTPS to the GAiA via same address.
GUI client -----> FW<----VPN---> R80.10 FW ----> R80.10 Mgmt Server
Checking the logs the packet from GUI client are logged in implied rule level and passing through the firewalls, and with fw monitor you can see the packets passing the R80.10 firewall and return packets from the management server truing to head back to the client, but the return packets get dropped because they are not SYN packets. It seems that there isn't any session associated with that initial passed packet and thus the return packets get dropped?
When checking the implied access control connection rules settings the only option is to disable them, you can't change order from the "First" to anything else.
Any idea how to allow access for GUI clients to the internal address with out disabling the implied rules and recreating them by hand?
