Can MAG (SSL VPN) act as a VPN concentrator for SSL VPN, IPSec, PPTP & L2TP? (Y/N)
I would recommend checking with your account team on PPTP & L2TP and, if needed, work with them for an enhancement request.
SSL VPN can serve SSL and IPSEC tunnels.
IKE V2 is also supported for dynamic VPN.
PPTP and L2TP is not possible.
Hope that answers your question.
