Correct, but that doesn't work with TOR. There are no port forwards. There are hidden services, but that's not really what you want.
When you're running in TOR just let it connect outbound and don't worry about trying to boost the number. You'll still get 8 which is plenty for a personal wallet.
Alright maybe this isn't the best way to boost my connections, but I still need to try some thing because:
I would really like to get more than eight connections because I'm mining.
For some reason lately I not getting even eight connections and I've already tried other options, for example; I've added about 30 addnode= commands to my bitcoin.conf file.
