First- great information, but not enough. Without seeing your router config, I can't tell if this is a lock in or poor routing script. Help us out on that.

Also- please post this to the Questions forum. Copy your original information and select the "Ask a Question" button. That will get you in front of people who answer questions but don't necessarily come to the discussion forum.

I really think that the answer is in your router config but can't even begin to point you without better information.

Try the "Questions" forum; the "Discussion" forum is for matters of general discussion, not specific problems in search of a solution.

Post problems such as this to the "Question" forum, rather than the "Discussion" forum. There are those who specifically seek out problems in need of a solution, and that's where they go to look for such.

Additionally there are the benefits that:

1) The "Questions" forum provides for your feedback, by way of your being able to mark "helpful" responses as such. This does not necessarily mean that a given response contained the complete solution to your problem, but only that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours, so that they might have a ready source of reference available, thereby perhaps obviating the need for them to repeat questions previously asked and answered.

2) The revised TR makes it quite difficult to find both "Discussions" and "Questions" that have not had a fairly recent post, owing to some functions comingling them in the listings. By keeping each type in their respective forums, it is easier for all to find what they are looking for.
