Looks like Graal is configured for UDP correctly in that case, just not your router.

You tried enabling DMZ? Though that would be a last resort, it seems to always work. I'll test the fixed port option later to confirm if it does turn UDP off like it did last time I tried. Maybe you could try setting fixed UDP option to another port, though I doubt that would work any better.

Not really sure how to help you if DMZ doesn't do it. Did you check if it works on V2 when everything's configured? I don't think it would be any different between 2 and 4, but I do remember people having problems or something with it in V4 and not V2. See, if we had a fast server in the USA, we wouldn't need UDP. That'll never happen, though, been waiting since October for a decent reply about this whole slow server problem.
