mdf: It seems to take a while (~10-15 seconds) for my ERL to assign a dhcp lease from clients first connecting. Is that normal or have I done something?
Nope that isn't normal - but, it is easy to fix:
set service dhcp-server shared-network-name LAN authoritative enable
Where LAN is your DHCP pool name.
Ta, that did the trick.
I've got two DHCP servers, one main and one for a guest network. Should I run this for both DHCP pool names, or is that stupid (you don't have two "authoritative" sources)?
