Hi arthurbox,
I'm sorry to hear that you're encountering these issues. If you've yet to do so already, I recommend reviewing the [url=https://www.bungie.net/en/Support/Troubleshoot?oid=12915]network troubleshooting guide[/url], particularly the portion concerned with NAT. Please bear in mind, however, that the guide is not a guaranteed solution, but rather a set of troubleshooting steps. I really hope this helps.
