This is explained further in our DHCP Server using Dnsmasq article. The latter method is advantageous because the EdgeRouter can cache the DNS information for the clients. If one client has previously resolved the IP address of a website, the next client will be able to access that IP slightly faster by resolving the address locally from the EdgeRouter rather than remotely from a global DNS server. Another benefit of using local DNS forwarding in EdgeOS is the option to resolve local hostnames easily when also using dnsmasq for DHCP. In this case, the DNS forwarding service is used and all client DNS requests are forwarded. Local Provide clients the EdgeRouter's IP address as the DNS server.In this case, the EdgeRouter's DNS forwarding service is not consulted. Global Provide clients global DNS server(s) using DHCP.EdgeRouter - Site-to-Site IPsec VPN with Many-to-Many Source NAT. I set the DNS to 1.1.1.1 at first, and I thought that could be the issue, so Ive since changed it to 8.8.8.8 and 8.8.4. You can test this with the nmap command nmap IPORFQDN -Pn -sU -p port changing. There are two methods that can be used to provide DNS services to clients: Browsing the internet normally everything seems super fast, except on this one site at least, where random requests just never seem to go through and hang indefinitely. Going back to the descriptions of those actions, netmap and same need a range of IP addresses, but dst-nat and src-nat only need a single address. The dnsmasq service runs in the background and will forward all client DNS queries to the specified DNS server(s). Per the description of to-addresses on Manual:IP/Firewall/NAT, it's used for dst-nat, netmap, same, and src-nat. Edge routers play a fundamental role as more services and applications begin to be managed on an organizations network edge rather than in its data center or in the cloud. The EdgeRouter forwards the DNS request from the client to a public DNS server.ĮdgeOS includes a DNS forwarding service based on dnsmasq that is consulted when clients use the EdgeRouter as a DNS server. In general, edge routers accept inbound customer traffic into the network.
