running into error while sending packages outside my local subnet

[chanti5099]

hello ,

while trying to send udp packages to a different subnet I received the following error.

Modifier: Destination 10.0.170.30 is off-subnet, looking up gateway
Error creating modifier: destination is off-subnet and failed to get gateway: default gateway not found.

The systems default gateway isn´t on the the sending interface in my case!
As well the device has several network interfaces.
And it seems that the function GetDefaultGateway() in pkg/modifier/gateway/linux.go doesn´t seem to find the route attached to the interface.

best
