Hi Guys,
I'm running Ubuntu 22.04 as a host (192.168.1.102) and Virtual Box Version 6.1.38 r153438 and have a Windows 11 Virtual machine. (192.168.103)
The VM can talk to the internet fine.
The VM's network interface is configured as a Bridged Adapter.
After disabling Windows Firewall I was able to ping the VM from the linux host and I could do a port scan and it shows the open ports on the windows VM. And I could telnet to port 445 of the vm as an example.
But, from the windows VM I can ping the linux host but cannot establish a connection to any open ports on the linux host.
Open Ports on my host.
Nmap scan report for user-All-Series (192.168.1.102)
Host is up (0.00016s latency).
Not shown: 998 closed ports
PORT STATE SERVICE
25/tcp open smtp
3389/tcp open ms-wbt-serveR
Open Ports on my win 11 VM.
Nmap scan report for 192.168.1.103
Host is up (0.00033s latency).
Not shown: 997 closed ports
PORT STATE SERVICE
135/tcp open msrpc
139/tcp open netbios-ssn
445/tcp open microsoft-ds
So why cant I for example, telnet from the windows VM to the Linux host. It just times out.
I also saw the following in my logs.

Any help would be appreciated.
