[OLSR-users] help in setting Freifunk what should I do to have a seamless network on top of Freifunk routers?

Filipe,

one more. You can of course *route* to a PC. The easy setup: Connect PC 
using ethercable to WAN port. Then configure WAN=Static with IP out of the 
Wifi netrange. PC eth also Wifi netrange and it has to run the OLSR daemon.

Here is a sample setup using the 14.123.x.x network for OLSR (other notation 
for this Network is 14.123.0.0/16, that means any OLSR/IP has to be between 
14.123.0.1 and 14.123.255.254, Broadcast is 14.123.255.255, Netmask is 
255.255.0.0:

PC1=14.123.3.65/30
WRT1(WAN)=14.123.3.66/30
WRT1(Wifi)=14.123.4.44/16
...
WRT2(Wifi)=14.123.251.88/16
WRT2(WAN)=14.123.88.1/30
PC2=14.123.88.2/30

/16 means: 255.255.0.0 netmask, /30 means: 255.255.255.252 netmask

Firewall on WRT(WAN) automatically disabled, because WAN(IP) is in the Wifi 
range. Also no NAT on WAN. OLSR is automatically sent on WAN too. The 4*LAN 
ports and the LAN NAT/Firewall setup will be intact.

The "micronetwork" beween WAN/PC has only 4 adresses. This setup using a 
very narrow netmask on WAN/PC connection has the advantage of being able to 
contact the WRT from PC without OLSR host routes - in case something is 
wrong / rotten / messed up.

PS.: the 14.x.x.x network is marked "Public Data Network" by IANA. So no web 
servers to expect in that range, maybe some old POS/POI systems from Wang or 
so. So no problem to hitchhike that address space :)
