salewski / cisco-asa-config.txt
Created July 28, 2018 16:50 — forked from benders/cisco-asa-config.txt
Getting Amazon VPC up and running with Cisco ASAs can be a pain. This is the config that we used to make it work.
! --------------------------------------------------------------------------------
! This example configuration shows what WE did to get Amazon VPC working with our
! ASAs. We use version 8.3(1). This config has not been reviewed or otherwise
! blessed in any way by anyone at Amazon. YMMV.
!
! It differs from Amazon's supplied config by using two different sets of
! crypto maps and ACLs, so it brings both tunnels up simultaneously.
!
! For the purposes of the example, the physical datacenter network is 172.16.1.0/24
! and the VPC is 10.0.0.0/16.
