VPNClient couldn't access Clients in LAN + Internet

[Minti]

Hi,

i have a problem by setting up a VpnServer with pfsense.
This is the test environment i used:

VPN Clients
                                      172.21.180.X/23
                                              |
                                              |
                                              |
GW to Internet–-------------WAN-IP Pfsense------------------LAN-IP Pfsense---------------------Client
172.28.204.2                      172.28.204.220                          10.20.0.2/24                                10.20.0.10
                                              |
                                              |
                                              |
                                        OpenVPN Service
                                        10.20.1.0/24

The client in my internal LAN(10.20.0.10) could access internet.
I could also connect to the openvpn service on the pfsense server out of the 172.21.180.0/23 network.
The VPN Client gets the IP-Adress 10.20.1.6 Gateway 10.20.1.5.
My problem is that the VPN Client couldn't reach the Internet or the internal LAN.

Here's my OpenVPN Config:
Server Mode: Remote Access (SSL / TLS)
Protocol: UDP
Device Mode: tun
Interface: WAN
Local port: 1194
Tunnel Network: 10.20.1.0/24
Force all client generated traffic through the tunnel
Compress tunnel packets using the LZO algorithm.
Provide a virtual adapter IP address to clients

Nat config:
Interface  source                dest
WAN        10.20.0.0/24        all
OpenVPN  10.20.1.0/24        all

Firewall rules
WAN allow UDP 1194
LAN Allow everything when source is LAN
OpenVPN allow everything

What do i have to do to access internal LAN and Internet from my VPN-Client?

Your OpenVPN server config does not mention what you put for "Local Network" and "Remote Network". On the server, you certainly need to specify "Local Network" - 10.20.0.0/24 - and that will be told to the clients.
