Dear Team,
we are having RUTX50 and wanting to allow our local network extension with 5g siem.
on 5g siem we are getting the IP and local connectivity is working properly with Nating but we don’t want to enable nating on RUTX50 as we got the firewall behind RUTX50.
we got DNS server behind firewall we disable NAT(Masquerading) on RUTX50,after disabling we are able to ping the DNS from our laptop but if we try to resolve the dns than its not working.
we dont see logs on firewall also for DNS query but if ping we are getting logs on firewall also.
please suggest how to check on RUTX50 deny traffic for the udp or dns request.
Could you please log in to the RUTX50 via CLI and execute the command: nslookup <domain_name> <DNS_server_IP> This will help us check if it returns the expected result.
Additionally, please try adding a traffic rule for DNS in Network > Firewall > Traffic Rules. The rule should allow UDP traffic on port 53 from your LAN to the DNS server.
If the issue persists, adding a static route in Network → Routing → Static routes could help. Ensure the route points to the DNS server’s IP address.
