I have problem with accessing oracle database with oracle SQL developer.
I'm using Watchguard m400 as my firewall/router and Windows Server 2012 R2 as Oracle DB Server.
I have server with local IP, lets say its 10.10.10.10, I NATted it with s-nat to a global IP one, let's say 126.96.36.199. I added a policy with ports 3389 - RDP and 1521 - oracle. I can RDP to that server's global IP (188.8.131.52) from local network or from public one, but unfortunatelly I can't acces via Oracle SQL Developer to that server at global IP (it works only from local network to local IP). Of course, on server I have oppened 3389 + 1521 in Windows Firewall.
My s-nat looks like this: From Any to 184.108.40.206 -> 10.10.10.10 Policy with ports 3389, 1521
