hi,

iam using a DEC750 with OPNsense 22.4_2-amd64 (business edition).

as soon as i enable IDS with or without IPS mode, my WAN interface link state is flapping (up/down).

When IDS is disabled all is fine. all hardware offloading is disabled.

i did not had that problem with OPNsense business 21.10

already tried a fresh reinstall.

any ideas?

greets
tom



But the interface in IDS is LAN? Are you using IPv6 tracking?

no, in IDS the interface is on WAN only

i dont have ipv6 enabled

LAN     igb0
WAN     igb1

and in IDS is WAN checked.

Can you provide us with dmesg output when turning IDS on and off and also IPS on and off?

Disconnects with IDS are highly unusual.

Also: any PPPoE involved?


Thanks,
Franco

i think its the same problem as this one

on my wan interface i use mac address spoofing (so i can get the same dhcp ip as my old router)
