Mysql: remote and local access

I have a gentoo where is installed a mysql server. I need a remote access to this server, so I have modified the option bind address in the file /etc/mysql/my.cnf bringing it from

bindaddress: 127.0.0.1

to

bindaddress: MY_FOREIGN_IP

And in this way I obtain a remote access to the mysql server.

The problem is that I have a local service that uses 127.0.0.1 ip to talk with my database. If I change the bindaddress option, this service can't reach mysql server anymore.

There is a way to solve this issue, without using ssh tunnel?
