That is of course a easy workaround. But changing the port on the
service IP would mean that the all customers would need to access SFTP
over a non standard port and the purpose of the whole exercise was to
provide a file transfer service over a simple standard port. Port 22
ticks all the boxes ;)

And changing the port for the internal IP would mean that that server
would be the only one running SSH over a different port, making it
none standard and require a lot of custom work for all our management
scripts.

P.S.: Oh, forgot to mention, this is on CentOS 6.4

Hoping the problem  magically goes away  by ignoring it is the
