Block specific range of WAN IPs to VPN Server
Is possible to block/allow only range of external IPs from WAN to LAN on VPN Server? Or setup a GEOIp-Block service like to VPNServer?
I tried to perform a kind of IP block using IPGroups for port 500 (IKE), but I was unsuccessful.
Can anyone help me?
VPNServer type: L2TP/IPSEC
