| 7 | 5 | Nico Schottelius | * You can use one of the known NAT64 prefixes from our networks (LINK!) |
| 8 | ** In the example below this is 2a0a:e5c0:2:10::/96 |
||
| 9 | * You need to have a /96 (or better: /64) routed to the openwrt |
||
| 10 | ** In the example below this is 2a0a:e5c0:17:1::/96 |

| 17 | # Load the kernel module |
||
| 18 | modprobe jool_siit |
||

| 20 | # The range which will be the target for the 2nd NAT (if needed to reach a v4 ip) |
||
| 21 | jool_siit -6 2a0a:e5c0:2:10::/96 |
||
| 22 | |||
| 23 | # Pick a v6 range to translate TO and a v4 range to translate from |
||
| 24 | jool_siit -e -a 2a0a:e5c0:17:1::/96 192.168.61.0/24 |
||
| 25 | |||
| 26 | # Accept Router Advertisements to keep the default address |
||
| 27 | sysctl -w net.ipv6.conf.all.accept_ra=2 |
||
| 28 | sysctl -w net.ipv6.conf.default.accept_ra=2 |
||
| 29 | sysctl -w net.ipv6.conf.eth0.accept_ra=2 |

| 33 | h2. Enabling routing with router advertisements |
||
| 34 | |||
| 35 | * By default ipv6 forwarding is on (good!) |
||
| 36 | * By default accept_ra is 0 |
||
| 37 | ** This does not set the route properly into the kernel -> routing is broken |
||
| 38 | * Need to modify accept_ra to 2 |
