1. DNS works on default settings
2. Adding L2TP/IPSEC layer, DNS only seems to work by using Tools>Traceroute and able to ping
3. Parallel, from Windows (or Linux), no ping and not DNS resolution
4. Tools>Torch on LAN interface shows requests to DNS IPs are being sent, but nothing gets returned
5. Tools>Torch on VPN interface shows requests to DNS IPs are bieng sent and returned
6. Seems as Mikrotik is not passing DNS to LANs

set allowed-interface-list=LAN1. Changed L2TP/IPSEC servers / Used the ones that other machines are working on with no problem to eliminate possibility of L2TP/IPSEC server issue
2. Used same DNS as on other machines that are presently working (10.10.10.10 - if private DNS)
3. Present active machines work without "Allow Remote Requests", tried with/without, still issues
4. Downgraded from 6.42 to 6.41 as most machines are on 6.41 working fine. Downgrade didnt change anything
5. Added rules strictly for DNS, no change
