SSH port change on TortoiseSVN

I set the following setting to change SSH port to a repository behind firewall:

[tunnels] ssh10022 = "C:\\Program\ Files\\TortoiseSVN\\bin\\TortoisePlink.exe -P 10022"

(Insert the above setting under "[tunnel]" part in the configure file of TortoiseSVN. The file can be opened from TortoiseSVN menu: [Setting] -> [General] -> [Subversion])

Using above setting, I can access the repository through ssh port 10022 like:

svn+ssh10022://user@host/path/to/repo"
