    Thanks very much, this helped me get my vyos to Azure VPN up and running.

    My network is a little differnt and I needed to specify:
    nat-traversal enable
    before it would work.

    Cheers,
    Rhys

    Hi, Thanks for your article. I am trying to set the same setup using your blog series. But my home router don’t have DD-WRT.

    you mentioned “Arguably, you do have the option to configure masquerade source NAT on the VyOS to avoid the need for this command but I despise double-NAT and wanted to avoid it at all costs.”

    If I still setup a NAT on vyos, something like below

    set nat source rule 10 outbound-interface ‘eth0’
    set nat source rule 10 source address ‘192.168.125.0/24’
    set nat source rule 10 translation address ‘masquerade’

    Eth0 – DMZ (where devices connected to home router)
    Eth1 – Internal (My domain controller, lab machines sit)

    Will it work? Do I need to follow special instructions anywhere?

    I managed to make it work. Since I am using NAT on Vyos, I need to exclude that NAT for Site to Site VPN to work.

    Thank you very much for such useful blog.
