[OLSR-users] Using the mesh to connect to the internet

[Lorenz Schori]

hi

yes, you have to setup your linux box (i assume you are using linux  
on your router machine) for nat (read network address translation).  
some resources:
- linux NAT howto: http://www.netfilter.org/documentation/HOWTO/NAT- 
HOWTO.html
- if you are using the gnome desktop you probably want to use  
firestarter and it's "internet connection sharing" feature: http:// 
www.fs-security.com/.

if you have additional questions about NAT i suggest you posting them  
to the mailing list of your linux distribution. it seems that you  
have configured olsr correctly but not NAT.

hope it helps
