Title: netmap_transmit em0 drop mbuff that need chechsum of flood
Post by: kkamran on June 02, 2023, 12:42:48 PM
Hi everyone and good day!

I have been trying to configure IDS/IPS for the last two weeks now on opnsnese version 23. Have done all updates.

Following all instructions as per book but as soon as I enable it, getting " netmap_transmit em0 drop mbuff that need chechsum of flood" error.

Can't access the web gui until reset it to default from the console.

I'm not Linux/Unix guy. Total experience in Windows. Just trying to build the firewall for Multi-WAN Failover and normal security.

Thanks in advance and best regards,
