You need to run /ip address print to “regenerate” the list, and then you can remove the second address,įinally, some settings do not have ID numbers. However if you then tried to run /ip address remove 2, the command line would return “no such item” (as you have already removed the second item in the list). For example if you deleted the second IP address ( 192.0.2.104/32) in the list above, this will move the third IP address to second in the list. If you want to change the address rather than deleting it, you would use commands like /ip address set 5 address=X.X.X.X/24 or /ip address set address=X.X.X.X/24.Īlso, the ID numbers are not always consistent. For example, to add an IP address to an interface on a MikroTik, you would do the following: -įlags: X - disabled, I - invalid, D - dynamicĤ D 192.168.122.208/24 192.168.122.0 ether3 RouterOS’s command line interface is unique in the networking world. I have used the extensively in my career, in everything from VPN concentration to regional layer 2 extensions. You are likely to see high resource usage and performance impact when enabling some of these features, but the fact they are available at this price level is astounding.īecause of the price and flexibility of MikroTik devices, they are a very popular option for smaller ISPs and WISPs (Wireless ISPs). Even on their hAP Lite (a £20 access point and router), they support packet captures, BGP, stateful firewalling, IPSec VPNs and more. MikroTiks have a reputation for being a networking Swiss army knife. You’d typically be looking in the multiple hundreds or thousands of pounds for a similar offering from other vendors. For example, I have a MikroTik RB4011 for my home router that has 10 single gigabit ports and 1 ten gigabit port. MikroTik are often significantly lower in price than what you’d find from other vendors. Their operating system (RouterOS) is built upon Linux, but unlike Arista EOS (or the BSD base of JunOS), you don’t typically have access to a Linux shell itself. MikroTik is a Latvian company who provide routing, switching, wireless and other networking devices.

However if the Mikrotik LAN interface is down when the IPSec tunnel is being established, then HQ is unable to access the loopback interface (even after PH1/PH2 successfully establishes) until the Mikrotik LAN interface is brought up.Īdd dh-group=XXXX enc-algorithm=XXXX hash-algorithm=XXXX name=PHASE1_XXXX nat-traversal=no proposal-check=exactĪdd address=2.2.2.2/32 exchange-mode=ike2 name=PEER_XXXX-XXXX profile=PHASE1_XXXXĪdd address=1.1.1.1/32 exchange-mode=ike2 name=PEER_XXXX-XX profile=PHASE1_XXXXĪdd auth-algorithms=XXXX enc-algorithms=XXXX lifetime=XXXX name=PHASE2_XXXX pfs-group=XXXXĪdd address=192.168.0.1/24 interface=loopback network=192.168.0.0Īdd auth-method=digital-signature certificate=XXXX.cer_0 peer=PEER_XXXX-XXĪdd auth-method=digital-signature certificate=XXXX.cer_0 peer=PEER_XXXX-XXXXĪdd action=none dst-address=192.168.0.0/24 src-address=192.168.0.0/24Īdd dst-address=0.0.0.0/0 peer=PEER_XXXX-XX,PEER_XXXX-XXXX proposal=PHASE2_XXXX sa-dst-address=1.1.1.1 sa-src-address=0.0.0.0 src-address=192.168.0.0/24 tunnel=yesĪny idea what we are missing on the config to enable hitting the loopback bridge interface from the IPSec tunnel when its member ports are down during IPSec establishment?Īdd address=192.168.255.1/32 interface=MGMT network=192.168.255.1Īdd dst-address=0.0.0.0/0 peer=PEER_XXXX-XX,PEER_XXXX-XXXX proposal=PHASE2_XXXX sa-dst-address=1.1.1.1 sa-src-address=0.0.0.0 src-address= sixth part of my ongoing series of posts on Ansible for Networking will cover Mikrotik’s RouterOS. If the Mikrotik LAN interface goes down AFTER the IPsec tunnel is established, HQ can still ping/connect to the Mikrotik loopback interface. However, currently HQ is only able to access the loopback interface if the Mikrotik LAN interface is up at the time the IPSec tunnel was established. We have an IPv4 loopback interface built on the Mikrotik for management, and would like HQ to be able to access this loopback interface via the IPSec tunnel at all times even if the Mikrotik's LAN interface is down. We are able to successfully establish PH1/PH2, and can pass traffic between both sides whether traffic is initiated from our HQ or from the remote Mikrotik CPE. On the 6.47.x code train specifically for new feature 'ipsec - allow specifying two peers for a single policy for failover'. We have IPSec configured between a Mikrotik CPE and our HQ location using a non-Mikrotik firewall.
