sh 一个shell脚本，为本地托管的nat VM创建一个8节点nat网络，通过por提供ssh，mysql，postgres和其他Web服务

Posted 2021-05-07

VBoxManage natnetwork add --netname natnet2 --network "192.168.15.0/8" --enable --dhcp on

for i in {2..8}
do
  # redirect ssh from default of 22 to 220#
  VBoxManage natnetwork modify --netname natnet2 --port-forward-4 "ssh${i}:tcp:[]:220${i}:[192.168.15.${i}]:22"
  # redirect mysql from default of 3306 to 330#
  VBoxManage natnetwork modify --netname natnet2 --port-forward-4 "mysql${i}:tcp:[]:330${i}:[192.168.15.${i}]:3306"
  # redirect postgres from default of 5432 to 540#
  VBoxManage natnetwork modify --netname natnet2 --port-forward-4 "postgres${i}:tcp:[]:540${i}:[192.168.15.${i}]:5432"
  # redirect nginx from default of 8080 to 880#
  VBoxManage natnetwork modify --netname natnet2 --port-forward-4 "nginx${i}:tcp:[]:880${i}:[192.168.15.${i}]:8080"
done

VBoxManage natnetwork start --netname natnet2
VBoxManage list natnetworks
