Re: Is port forwarded connection taken as local?

So in another word, 'myusername'@'localhost' was denied access if connecting via port forwarding, but it's allowed access if connecting from localhost. Hence my question, if port forwarded connections are really taken as local connections??? But on server2, the following command works fine. server2% mysql -h localhost -u myusername -p I'd appreciate if anybody would shed some light.

Re: Is port forwarded connection taken as local?
in port forwarding , all you are saying is !!ok, if server1 gets any connection on port 3307 then forward that connection to port 3306 on server2, so essentially the connection on server2 for Mysql is coming from the client on server1 , so the user you are using to connect to server2 from server1 has to have permissions to connect to server2 from server1 ( Note: the user might have permission to connect to server2 from server2 itself, but not from server1). So please add that permissions appropriately on server2 as you told earlier On server2 GRANT ... TO 'someuser''@'server1' identified by 'password' That would solve it ... You also asked if port forwarded connections are really taken as local connections??? in this case a connection on server1 was port forwarded to server2 , so server2 does not see this connection as being local...
