| 18 | | For now, I'm considering this resolved. Error due to an old and incorrect configuration for host adapters. |
| | 18 | For now, it appears we've identified what is changing the network adapter (bad config carried over from older installation of vbox.). |

| | 20 | However, the original issue remains in that upon reboot of my computer, Multicast stops working. |
| | 21 | |
| | 22 | Non-working state after reboot: |
| | 23 | netstat -nr |
| | 24 | Network Destination Netmask Gateway Interface Metric |
| | 25 | 192.168.56.1 255.255.255.255 On-link 192.168.56.1 281 |
| | 26 | |
| | 27 | Working state after setting metric to "800": |
| | 28 | netstat -nr |
| | 29 | 192.168.56.1 255.255.255.255 On-link 192.168.56.1 1056 |
| | 30 | |
| | 31 | Re-enabling automatic metric still allows Multicast traffic through: |
| | 32 | netstat -nr |
| | 33 | 192.168.56.1 255.255.255.255 On-link 192.168.56.1 281 |
| | 34 | |
| | 35 | I compared the output of the non-working netstat -nr (Left) and the working netstat -nr (Right). Both are set to automatic metric. (Diff between non-working and working netstat -nr.png) |
