*Bump* (Sorry!)
Anybody got any ideas on this - it happened again last night - a reboot of both devices cured it (as usual)...
For more info - I have NAT enabled on the Linksys device....should that be set to disabled and will I need to put a static rout into it?
And on other odd thing - even though I have DHCP Relay configured to point to the Zyxel (102.168.10.1) on the Linksys, it still asks for a starting address and pool size...not sure why it would need that!
