You could try, but they may be unable to help you. You can also look around and see if you can get any more help on the issue. Other than that, you could always try a different router. It may be a good idea to ask here for good routers that don't give you problems with sending to yourself (and, for that matter, ones that also don't give you problems with RESUME because of the NAT settings in the router).

You might want to post your router here as someone here may have the same router and could verify if the router is the problem.
