Note: If using shared to other computers networkmanager will take care of sharing ipv4 and ipv6 internet. If using manual IP add required FORWARD rules in iptables.
To ping IPv6 add sudo ip6tables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

Jool Installation

• Build the jool modules using below build instructions
  

  Code Block
  title Jool Installation
  sudo apt update sudo apt upgrade sudo apt install build-essential pkg-config sudo wget https://github.com/NICMx/Jool/releases/download/v4.2.0-rc2/jool-4.2.0.rc2.tar.gz sudo tar -xzf jool-4.2.0.rc2.tar.gz sudo /sbin/dkms install jool-4.2.0.rc2/ cd jool-4.2.0.rc2/ sudo ./configure sudo make sudo make install

• Once build completed, below modules will be generated in respective paths, add those modules to kernel path
  

  Code Block
  title MAPT Modules
  ubuntu:~/jool-4.2.0~rc2$ find . -iname jool*ko ./src/mod/mapt/jool_mapt.ko ./src/mod/common/jool_common.ko ./src/mod/nat64/jool.ko /src/mod/siit/jool_siit.ko

  Jool configure

  Code Block
  title Modeprobe modules
  sudo modprobe jool_common sudo modprobe jool_mapt sudo modprobe jool Enable below modules as well if not enabled netfilter/nf_defrag_ipv4.ko netfilter/nf_defrag_ipv6.ko

• Once all modules are loaded and confirmed via lsmod

  Expand
  title lsmod

• Create an instance BR
  

  Code Block
  title BR instance creation
  sudo jool_mapt instance add "BR" --netfilter --dmr 64:ff9b::/64 sudo jool_mapt -i "BR" fmrt add 2001:558:6013::/48 192.168.20.0/24 8 8 sudo jool_mapt -i "BR" global update map-t-type BR
