 h1. Managing OpenWRT 

 h2. Installing and configuring Jool 

 <pre> 
 opkg install kmod-jool 
 opkg install jool-tools 

 # Load the kernel module 
 modprobe jool_siit 

 # The range which will be the target for the 2nd NAT (if needed to reach a v4 ip) 
 jool_siit -6 2a0a:e5c0:2:10::/96 

 # Pick a v6 range to translate TO and a v4 range to translate from 
 jool_siit -e -a 2a0a:e5c0:17:1::/96 192.168.61.0/24 

 # Accept Router Advertisements to keep the default address 
 sysctl -w net.ipv6.conf.all.accept_ra=2 
 sysctl -w net.ipv6.conf.default.accept_ra=2 
 sysctl -w net.ipv6.conf.eth0.accept_ra=2 

 </pre> 


 h2. Enabling routing with router advertisements 

 * By default ipv6 forwarding is on (good!) 
 * By default accept_ra is 0 
 ** This does not set the route properly into the kernel -> routing is broken 
 * Need to modify accept_ra to 2
