I've never had a problem with this before. Just set up my new DIR-825 today. I own my own domain and have it hosted... I'm simply trying to get the DIR-825's email function to work.
When I try (for example) emailing the logs, the SMTP process fails. It appears the failing point is that the SMTP server is sending an inbound IDENT (TCP port 113) request, and the router is blocking it. This makes the SMTP process fail.
I can't (and don't want to) disable IDENT on the SMTP server. I have no idea how to make this work. Ideas, please?
