We will use RouterOS built-in proxy server running on port 8080.A new window will be opened with the novnc console. This can be achieved by redirecting HTTP traffic to a proxy server and use an access-list to allow or deny certain websites.įirst, we need to add a NAT rule to redirect HTTP to our proxy.
Sometimes you may want to block certain websites, for example, deny access to entertainment sites for employees, deny access to porn, and so on.
Without this rule, if an attacker knows or guesses your local subnet, he/she can establish connections directly to local hosts and cause a security threat.įor more detailed examples on how to build firewalls will be discussed in the firewall section, or check directly Building Your First Firewall article. This rule allows established and related connections to bypass the firewall and significantly reduce CPU usage.Īnother difference is the last rule which drops all new connection attempts from the WAN port to our LAN network (unless DstNat is used). In-interface=ether1 comment="drop access to clients behind NAT from WAN"Ī ruleset is similar to input chain rules (accept established/related and drop invalid), except the first rule with action=fasttrack-connection. The simplest way to make sure you have absolutely clean router is to runĪdd chain=forward action=fasttrack-connection connection-state=established,related \Ĭomment="fast-track for established,related" Īdd chain=forward action=accept connection-state=established,related \Īdd chain=forward action=drop connection-state=invalidĪdd chain=forward action=drop connection-state=new connection-nat-state=!dstnat \ If you see the router in the list, click on MAC address and click Connect. Now open WinBox and look for your router in neighbor discovery. If there is no default configuration on the router you have several options, but here we will use one method that suits our needs.Ĭonnect Routers ether1 port to the WAN cable and connect your PC to ether2. Since this article assumes that there is no configuration on the router you should remove it by pressing "r" on the keyboard when prompted or click on the "Remove configuration" button in WinBox. When connecting the first time to the router with the default username admin and no password ( for some models, check user password on the sticker), you will be asked to reset or keep the default configuration (even if the default config has only an IP address). This document describes how to set up the device from the ground up, so we will ask you to clear away all defaults. The quick guide document will include information about which ports should be used to connect for the first time and how to plug in your devices. More information about the current default configuration can be found in the Quick Guide document that came with your device. When no specific configuration is found, IP address 192.168.88.1/24 is set on ether1 or combo1, or sfp1.
