Bienvenidos a CarlosMorenoTutoriales, hoy os enseñaré a configurar el Firewall de un Router Mikrotik.Layer7protocol:-. Discusses firewall best practices and standard default firewall configurations that can help protect networks from attacks that originate outside a. I remember my old Cisco router’s config – I used it to forward OpenVPN incoming connections (on a non-standard 7620 port) to other (non-Cisco) router behind… Maybe I should declare in GUI (the CLI’s commands are awful) in IP -> Firewall -> Filter notes -> add new… IN interface pppoe-out/dynamic (instead WAN/ether1) ? ![]() I watched many tutorials (especially on Youtube), but no one helped me. I am using a pppoe connection to connect to my ISP from my router and I would like to set up a L2TP-IPsec server too on the same router. It’s an old post, so, please accept my humble apologies for bothering you. If you want to avoid pasting commands into the cli you can create these firewall rules in winbox, here are some screenshots. ip firewall filterĪdd action=accept chain=input dst-port=500,1701,4500 in-interface=ether1 protocol=udp \Ĭomment="allow L2TP VPN (500,4500,1701/udp)" The ruleset can be further condensed by combining the 3 udp rules into one. These rules must be placed above any deny rules on the “input” chain. L2TP/IPSec Firewall Rule Set /ip firewall filterĪdd action=accept chain=input in-interface=ether1 protocol=ipsec-esp \Īdd action=accept chain=input dst-port=1701 in-interface=ether1 protocol=udp \Īdd action=accept chain=input dst-port=4500 in-interface=ether1 protocol=udp \Īdd action=accept chain=input dst-port=500 in-interface=ether1 protocol=udp \ When you configure a L2TP/IPSec VPN on a MikroTik RouterOS device you need to add several IP Firewall (Filter) rules to allow clients to connect from outside the network.
