Just upgraded to Version 4.6 on my VPN100...
I experienced a not working DNS Zone forward (VPN100 as vpn server) trough my site2site vpn tunnel.

specific dns *.domain.xy should be queried from
don’t work in v4.6

I deleted the rule and entered it again, but no change.


I rebooted on previous version V4.35(ABFV.3). everything is working fine.
I’ll stay on the old version, until Zyxel reviews and solves this bug.


Best regards

    So your VPN site2site for VPN100 whats the remote policy IP by and by what device? and local policy ?

    What happens if you put * only to forward to DNS server ?

    Do the logs show any blocks from VPN tunnel to LAN1?
