TCP/IP protocol suite: Firewall and NAT - stateful packet filtering; Peer-to-Peer protocol filtering; source and destination NAT; classification by source MAC, IP addresses (networks or a list of networks) and address types, port range, IP protocols, protocol options (ICMP type, TCP flags and MSS), interfaces, internal packet and connection marks, ToS (DSCP) byte, content, matching sequence/frequency, packet size, time and more...

Configuration possibilities RouterOS provides powerful command-line configuration interface. You can also manage the router through WinBox - the easy-to-use remote configuration GUI for Windows -, which provides all the benefits of the command-line interface, without the actual "command-line", which may scare novice users. Web-based configuration is provided for some most popular functionality.
Major features: Clean and consistent user interface Runtime configuration and monitoring Multiple connections User policies Action history, undo/redo actions safe mode operation Scripts can be scheduled for executing at certain times, periodically, or on events. All command-line commands are supported in scripts
Router may be managed through the following interfaces (note that until a valid IP configuration is enteres, telnet and SSH connections are not possible):
Local teminal console - AT, PS/2 or USB keyboard and VGA-compatible video controller card with monitor
Serial console - any (you may choose any one; the first, also known as COM1, is used by default) RS232 asynchronous serial port, which is by default set to 9600bit/s, 8 data bits, 1 stop bit, no parity, hardware (RTS/CTS) flow control
Telnet - telnet server is running on 23 TCP port by default
SSH - SSH (secure shell) server is running on 22 TCP port by default (available only if security package is installed
MAC Telnet - MikroTik MAC Telnet potocol server is by default enabled on all Ethernet-like interfaces
Winbox - Winbox is a RouterOS remote administration GUI for Windows, that uses 8291 TCP port. It may also connect routers by their MAC addresses
