Native/Emulated Mode Netmap

[yeraycito]

Mini-Pc Opnsense 23.7.3

-Wireguard
-Suricata ( Wan )
-Zenarmor ( Routed mode L3 native Netmap ) Lan + LAGG

Interfaces ( Igb ):

-Wan
-Lan
-Wg
-LAGG

Access to Opnsense via SSH: sysctl -a |grep netmap

Native Netmap does not work.

[yeraycito]

I add a new Tunable dev.netmap.admode=1 and restart Opnsense. Zenarmor does not work at startup

[yeraycito]

In Zenarmor I change the mode to Routed L3 emulated Netmap and then it works.

The Tunable created above has modified itself.

Are you working up your posts number?

Use the 1st post and edit/modify by adding your additional comments...

edit: from netmap man page.

dev.netmap.admode: 0
             Controls the use of native or emulated adapter mode.

             0 uses the best available option;

             1 forces native mode and fails if not available;

             2 forces emulated hence never fails.

The size of the images to upload is limited in each comment so in order to put them all I need to create several comments.

dev.netmap.admode: 0      Native Netmap not working - Zenarmor working ( Native Netmap driver )

dev.netmap.admode: 1      Native Netmap not working - Zenarmor not working ( Native Netmap driver )

dev.netmap.admode: 2      Native Netmap not working - Zenarmor working ( Emulated Netmap driver )

Did you try native with the -tun kernel ? It looks like the emulation might be going away - or at the very least not be the only option available - thanks to a patch from the Zenarmor team
