Dialup VPN trafic from lan to client

Hi everyone. I have a working L2TP VPN. Clients can connect and use resources inside the LAN. However, form the LAN side, I would like to be able to connect to the VPN client using e.g. RDP or simply ping it. What must be done to achieve this?

The only firewall rule for the VPN i have is:
chain=input action=accept protocol=udp dst-port=4500,500,1701 log=yes
log-prefix=“VPN”

Hi,
I’ve no experience with L2TP VPN but I’ve a working OpenVPN configuration.
I can ping my clients and probably can connect to services. I’m not aware that I added firewall rules to enable this.

Can you rule out the the client has some kind of firewall that blocks all connection attempts? Can you connect to the client when it is connected via WiFi/LAN?

Yes, I can ping the client. I didn’t think about it when writing this message but his windows had the network set to public and it was the firewall blocking incoming ping. No extra rules.

That sounds great. Your problem is solved then? RDP is working, too?

Gosh, I didn’t actually check it … I’ll try tomorrow, because now I have no option.
