When having layered service provider issues, it is great to know that a tool like Komodia.com is available as an invaluable resource.  There is the free LSP guide and the free LSP resource page and the free LSP newsletter.

A problem installed LSP can seem like the loneliest problem in the world, but there is help available and it is only a click away.  For every problem that you cannot solve, Komodia will have an answer.
