If I use Nmap with this command line to scan nmap -sU -p 68 -Pn --reason 172.26.228.199 (only UDP port 68 on .199 host)
I get back
Starting Nmap 6.47 ( http://nmap.org ) at 2016-01-11 14:21 Central Standard Time
Nmap scan report for 172.26.228.199
Host is up, received arp-response (0.0045s latency).
PORT STATE SERVICE REASON
68/udp filtered dhcpc port-unreach from 172.26.228.84
MAC Address: 00:0C:29:1D:D8:41 (VMware)
Nmap done: 1 IP address (1 host up) scanned in 1.92 seconds
The response from the .84 is the host OS that is running windows 10 with vmware workstation pro v12.0.0 and NOT the .199 guest OS. I have tried this with a Kali guest as well and got same results.
I am using bridge mode. I also, tried disabling the DHCP options for both the the host only and nat networks as well as disabling and unchecking the connect host to virt adapter and no change.
I discovered this while trying to lock down all ports on a guest OS with the firewall and could do it except for port 68 then I added the --reason and saw this.
Thanks for any help
