IKEv2 VPN not seeing local DNS
I've got a M290 running the latest firmware (12.9.4) and up until about 3 days ago I had a working IKEv2 Mobile vpn working properly.
Now when I log in the remote user isn't getting the local DNS server at all. I've setup logging on both the DNS and Allow.IKEv2 policy and the only DNS requests I can see are to DNSWatch or other public DNS server. I get no name resolution whatsoever when connected to the VPN.
Through testing I've set the VPN to use the network configuration and specified the DNS servers directly within the VPN configuration. I've tried split tunneling, and I've tired forcing all traffic through the tunnel (our preferred method). All with the same result.
I've restarted servers and firebox. Verified DNS is working internally but I can't get any joy on the mobile VPN.
captured data using "-i vlan20 -n host XXX.xxx.XXX.xxx" doesn't even register the VPN ip address in wireshark.
It's as though the Mobile VPN doesn't see the anything on the local network.
