If you have a decent password (on all accounts) I wouldn't worry about 
about it too much.  Move it to an odd port or even require a client 
certificate if your client software supports it.

The usual problem with IPSec is trying to make it work through a NAT 
router.   Does your server have a public address of its own?   SSL and 
OpenVPN can work through port-forwarding routers.
