Hello,

I tested with multiple interfaces and seems to work OK, tested in
combination with -a option. The only issue that was leading to confusion was
the port scanner modules (openvas_tcp_scanner.c), which are NOT setting the
source addr given by -S, so part of the traffic still goes as the primary
source address.

Thanks for the tip!

Thanks,
Chandra.
