introduction

  • bastion host
  • screened subnet
  • dual firewalls

what it is

 

Each perimeter firewall acts as proxy server so it can hide the LIC addresses. All packets leaving the LIC are edited and all the internal addresses are hidden by replacing them with the firewall's own address. This is a security feature that keeps the true LIC addresses secret.
