This is an OpenWRT feed with a Linux kernel module implementing hacky NAT26.
With Barrier Breaker (trunk), add the following line to feeds.conf.default:
src-git nat26 https://github.com/codefetch/nat46.git
then issue:
./scripts/feeds update -a
./scripts/feeds install -a -p nat26
This will cause the following to appear in the "make menuconfig":
- Kernel modules -> Network Support -> kmod-nat26
The management of the NAT26 interfaces is done via the /proc/net/nat26/control file.
For more information about the module, take a look at the nat26/modules/README file.
