Added support for capturing virtualized traffic. ## VXLAN https://en.wikipedia.org/wiki/Virtual_Extensible_LAN VXLAN implemented as separate engine, which opens UDP socket and awaits traffic. This approach is made to work with AWS Traffic Mirroring. In order to enable VXLAN set `--input-raw-engine vxlan` Example: ``` gor --input-raw :80 --input-raw-engine vxlan --output-stdout` ``` By default, it looks for vxlan traffic on the standard 4789 port, but you can override it with `--input-raw-vxlan-port`. Additionally, you can allow only specific VNIs using `--input-raw-vxlan-vni`, or disallow by using the same option, but by adding "minus" sign to the value: `--input-raw-vxlan-vni -2`. Example with all options: ``` gor --input-raw :80 --input-raw-engine vxlan --input-raw-vxlan-vni 1 --input-raw-vxlan-vni 2 --input-raw-vxlan-port 2222 --output-stdout ``` # VLAN https://en.wikipedia.org/wiki/IEEE_802.1Q VLAN protocol enabled using `--input-raw-vlan` argument, and you can filter for specific VLAN VIDs using `--input-raw-vlan-vid`. VLAN filtering happens on BPF level. Example: ``` gor --input-raw :80 --input-raw-vlan --input-raw-vlan-vid 1 --output-stdout` ``` ## Notes Did a refactoring of RAW Input options, so it will be easy to extend in future.
