It looks like there is an issue since 3.0 that they have removed IP Helpers. I will keep looking.

Yes I have that enabled already. In fact, on other MT systems that carry the backhaul (no firewall or nat) I also enabled this just to be safe. Version 2.9.x has a helper for GRE and PPtP, version 3.x only has PPtP, in these firewall 'helpers'. My border system is version 3.10. I need to make progress on this issue, since a couple customers have gone into town to other hotspots and have no trouble, so my "network is to blame".
