Hello,
VPN clients connected to my WinSrv2019 RRAS server can't reach another computer on the same LAN as the VPN server.
(VPN Server with one interface card).
Here is the configuration
My LAN is 172.22.200.0/22, which corresponds to addresses 172.22.200.1 - 172.22.203.254 (subnet mask 255.255.252.0)
The VPN server IP address is 172.22.200.5.
The IP range for VPN clients is 172.22.201.1 to 172.22.201.10 (so they get LAN addresses)
Authentication works fine (IKE + NPS Radius server)
The VPN server internal network interface gets 172.22.201.1 IP address
The first VPN client connected gets 172.22.201.2
The VPN client is able to ping 172.22.201.1
The VPN client is able to ping 172.22.200.5 (LAN Interface of the VPN server)
But the VPN client has no answer while pinging 172.22.200.4, which is another server (firewall off...) on the same LAN as the VPN server.
With wireshark installed on the VPN server I can see ICMP request going out to 172.22.200.4, but no answer.
IP forwarding is enabled on the VPN server.
I can't understand what happens, and I already lost hours on this issue.
Any help will be appreciated and welcome :)
Laurent
