Questions about always on VPN and DHCP

Hello,

We are trying to replace our DirectAccess server with Always on VPN. However I am running into some trouble trying to set it up.

  1. Is it necessary to set up the DHCP scope for the always on VPN network subnet?

If so,

  1. Does the always-on VPN server need to have an IP address in this subnet or does it just need to be able to access it?
  2. Is it ok to use our firewall as the DHCP server rather than setting it up on a Windows server?

Thank you

    So I believe I found a partial answer to my question. I found where I can set a static IP address pool. However I don't see where to set up the DNS servers or default gateway. Does the VPN server itself take care of all of that?

    The vpn clients will inherit DNS addresses from the RRAS server's own connection properties. Since VPN is point-to-point there is no need for a default gateway.
