Hi Lars

Firstly, what equipment are you using?

Currently your access points and repeaters must only be doing Layer 2
routing. Layer 3 should be left to the hotspot. This means you shouldn't
need DHCP relays, and your access points and repeaters IP's shouldn't be on
the grase network (mostly for security, but also so they don't interfer
with a client). They should be setup as "ethernet bridges", with all Layer
3 (IP addresses and such) handled by grase.

The best way to think of it, is they should be setup transparently like an
ethernet switch. You don't know how many ethernet switches are between you
and a server, just how many routers. If you can tell how many wireless
devices are between you and the server (due to IP routing instead of
Ethernet routing) then they are setup wrong.

Let us know what model equipment you have, and the settings in them.
