opnSense reply-to & AWS' source/destiny check

0 minute read

Never forget those two things:

  • disable the AWS source/destiny check
  • disable the reply-to check (functionality?) in opnSense (Firewall -> Settings -> Advanced)
    • interestingly, this applies to “WAN interfaces” according to the help string, yet my instance only has a LAN interface … 🤷🏼‍♂️
