Not too familiar with airlink but it perhaps doesn't happen to have a
(ALG)/Application Layer/Level Gateway in it does it ?

If so I could reccomend attempting to turn it off. Ive seen this
similiar sort of thing in other routing equipemnt that either didn't
work at all or would bomb out on particular services.

The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume.
