Server working, Clients can connect, no network connectivity

I have successfully set up a WireGuard Server at my home on Ubuntu in a virtual machine behind a NAT firewall.

I can sucessfully connect with Windows TunSafe or IOS WireGuard app both from internal and external network. Connect is very fast and reliable.

But as soon as the client is connected, I cannot access any IPs in my local network nor can I access the Internet. Seems to be some routing issues.

I have used following IP addresses: on my internal Network, Default GW: on the tun Network .1 Server, .2 Client used on LTE Access Point to test external access

Here is the connection log (official IP and DynDNS obfuscated):

[18:58:29] Loading file: C:\Program Files\TunSafe\Config\walter.conf

[18:58:29] Added Route  =>
[18:58:29] Sending handshake...

route print on windows looks like this after connected:

IP addresses on wireguard server:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:9f:26:cf brd ff:ff:ff:ff:ff:ff
    inet brd scope global noprefixroute ens33

    inet6 fe80::d92a:ef26:75ab:4353/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: wg0: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1420 qdisc noqueue state UNKNOWN group default qlen 1000
    inet scope global wg0
       valid_lft forever preferred_lft forever

Do I need to configure any routing on my Ubuntu Server?

Any ideas how I can fix this?
