Hi!

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 192.168.1.3
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

Stefan

    So this is by DNS Domain Zone Forwarder are you use Public DNS server or private DNS server if using private try public by query via the zone of  192.168.1.3

    So your VPN site2site for VPN100 whats the remote policy IP by and by what device? and local policy 192.168.1.0/24 ?

    What happens if you put * only to forward to DNS server 192.168.1.3 ?

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