WordPress database connection issue, force TCP over localhost

Hello everyone,
I am trying to connect to a remote mysql database which is tunneled on my machine(localhost). I use the following parameters to connect to it

$ mysql --protocol=TCP -P 10000 -h localhost -u username -p'password' db_name

2 rows in set (1.38 sec)

as you notice the above connection works just like normal connection except it take the following extra parameters:

Port = 10000
Protocol = TCP
Host = localhost

I was wondering how do i set the the above in wp-config.php, so wordpress can connect to the remote database just like mysql CLI client was able to.

Let me know, if anyone has any ideas. Thanks
