...bernd's right: I read that stuff here. Besides the technical issues, the
OLSR-DHCP function was meant for attracting new users for mesh networking.
Over time, focus has changed - so the DHCP function is a point one on my
- For a stable network, we need a) long time users and b) people with a
correct network setup and c) people using good antennas. This is generally
not true for a) windows whiners, b) for client-firewall-block-it-all
software and c) for PCMCIA card owners -> see the "how do i configure my pc
for IP forwarding" thread.
- It's more easy for non-experts to simply attach a cheap access point (go
to the flea market and buy that stuff for $10) to the mesh device offering
DHCP/NAT/Easy setups in their cafe / student flat / public room for that
kind of function.
- DHCP attracts the wrong folks, basically spongers.
- Too many questions from blokes who refused to read their "Netmask and IP
setup basic instructions for the entry level admin" manual.
Hence my hint: Use IPv6 to deploy autoconfig. Use fixed IP settings
