While all options are important for a complete setup, the most common reason LAN devices with correct IPs cannot reach the internet is the absence of Source NAT (masquerade). This rule translates private LAN IPs to the router’s public IP, allowing outbound traffic to traverse the internet and ensuring return traffic comes back correctly.

Symptoms of poor performance and disconnections after a new AP is installed nearby strongly suggest wireless interference or channel congestion. The Spectrum Analyzer shows channel utilization and noise from all sources, while the Wireless Sniffer can reveal details about neighboring networks (SSID, channel, signal strength), helping you choose a less congested channel.

Firewall rules are processed from top to bottom. The correct approach is to first create an explicit accept rule for the trusted IP on the specific service ports (80, 443). Then, a drop rule for the same destination ports on the WAN interface will block all other connection attempts. Option B would block the trusted IP because the drop rule is evaluated first.

While providing DNS servers is crucial for a functional network, it is not strictly mandatory for the DHCP Server Network configuration to be created and active. The mandatory parameters are the Network (address/prefix), the Gateway, and at least one Address Pool. DHCP clients may still get an IP without DNS, but they won’t be able to resolve domain names.

The command `/ip route print` shows the status of all routes. You should look for your static route and check two key columns: ‘Distance’ (should be lower than any alternative route) and most importantly, the ‘Gateway Status’. If the gateway is unreachable, it will be marked as such, indicating the router cannot ARP for or communicate with the next-hop 192.168.1.200, despite your successful ping from a different context.

PPPoE adds an 8-byte header to frames, reducing the effective MTU to 1492. If the router’s MTU is 1500, TCP packets with a 1500-byte MTU will be fragmented or have the DF (Don’t Fragment) bit set, causing issues. Setting the MSS to 1430 (1500 – 40 IP/TCP headers – 8 PPPoE – 22 safety margin) in the PPPoE client profile instructs clients to use smaller TCP packets, preventing MTU-related path failures, a very common issue with PPPoE.

FastTrack is a performance optimization feature. Once a connection is established and tracked by the firewall (e.g., via a related/established accept rule), subsequent packets of that connection are ‘fast-tracked’. This means they bypass the firewall filter, NAT, and connection tracking processes, significantly reducing CPU load and increasing data throughput for that flow.

A Simple Queue is the correct tool for per-IP or per-subnet bandwidth limiting. You create a new simple queue, specify the target IP address with a /32 mask (for a single host), and then set the ‘Max Limit’ under the ‘Download’ column to 5M (or 5Mbps). This will enforce the 5Mbps download limit for traffic destined to that IP.

MikroTik backup (.backup) files are largely hardware and RouterOS version-specific. A backup from one model (e.g., an RB2011) often cannot be restored to a different model (e.g., a hEX) or to a much older/newer version of RouterOS because of differences in drivers, architecture, and supported features. This is a common restoration hurdle.

While all options are important for a complete setup, the most common reason LAN devices with correct IPs cannot reach the internet is the absence of Source NAT (masquerade). This rule translates private LAN IPs to the router’s public IP, allowing outbound traffic to traverse the internet and ensuring return traffic comes back correctly.0
