General Discussion / Re: Suricata not starting on one WAN interface

Hello Franco,
I narrowed it down the one of these that need a change, not sure which one though.
dev.netmap.buf_num: 163840
dev.netmap.ring_num: 200
dev.netmap.buf_size: 2048
After reading the Man Pages, here is what I have got:
"netmap supports raw packet I/O through a port, which can be connected to a physical interface (NIC), to the host stack, or to a VALE switch). Ports use preallocated circular queues of buffers (rings) residing in an mmapped region. There is one ring for each transmit/receive queue of a NIC or virtual port. An additional ring pair connects to the host stack.
Sizes and number of objects (netmap_if, netmap_ring, buffers) for the global memory region. The only parameter worth modifying is dev.netmap.buf_num as it impacts the total amount of memory used by netmap."
I will try to tweak these values and see if this resolves the issue.
Thanks and Regards,
