Hi.
I'm running Zorin 16.2 Pro with upgraded kernel 6.3 on my system.
I'm able to perform outbound connections, e.g. the internet, connect other Samba/SSH servers on the LAN but can't perform any inbound connections from external systems.
The LAN is on the wifi adaptor:
sudo lshw -c network

The firewall is disabled:

Dec 12 12:00:22 XXXX-XX-XXXX systemd[1]: Starting Samba SMB Daemon...
Dec 12 12:00:22 XXXX-XX-XXXX systemd[1]: Started Samba SMB Daemon.
But when I try to ping from external systems:
ping 192.168.1.117
PING 192.168.1.117 (192.168.1.117) 56(84) bytes of data.
From 192.168.1.107 icmp_seq=1 Destination Host Unreachable
When samba from external system:
smbclient -L 192.168.1.117 -U XXXX
do_connect: Connection to 192.168.1.117 failed (Error NT_STATUS_HOST_UNREACHABLE)
Note device isolation is disabled on the wifi router as the reverse samba call works.
Any ideas why this is happening?
Thanks in advance for any help with this.
