Managing OpenWRT

Installing and configuring Jool

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

# 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

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
