L2TP/IPSEC VPN from multiple NAT IPs

  • Hello,

    We just replaced a Meraki MX60 for a client with pfSense. The client was using L2TP/IPSEC VPN with Windows authentication for remote users and we were able to set that up as well, requiring a minimum of client config changes (L2TP/IPSEC with RADIUS auth via Network Policy service)

    The client has a couple remote offices (behind NAT firewalls) where 2+ individual users were able to connect the VPN at the same time, but with the pfSense in place, that does not seem to be possible; only one user at a time can connect to the VPN at the same time.

    I am guessing Meraki has a diferent implementation of L2TP/IPSEC that allowed multiple connections from the same NAT IP, or is there a setting I can change in pfSense to allow this?

    Thanks, in advance, for your insight and advise.
