I created L2TP vpn (ipsec) server (on RouterOS 7.8 ). It works correctly, I can establish VPN connection (from Win10).
But when I enable BCP (//PPP/Profile - Bridge), it has no effect, the L2TP interface is not bridged.
What's wrong?

I have trouble with OVPN server. When ovpn user connects to the server, in routing table appears: ADS 192.0.0.0/8 <ovpn-jmarek> 1 Why is there prefix /8 ??? I use ROS 6.48 . interface ovpn-server server print enabled: yes port: 1194 mode: ip netmask: 24 mac-address: FE:F2:63:8D:BE:4B ... default-pro...

I have CCR1036. I use VLAN bridging there. Until now I used VLAN bridging as making VLANs on each port and connect them in the bridge. (vlan100-1 on eth1, vlan100-2 on eth2 and add interfaces vlan100-1 and vlan100-2 to the bridge). I studied documentation and found that this way is wrong. Correct se...

When I'm doing bandwith test between two routerboards, sometime happends, that it runs corectly in one direction, but on second direction it shows 0 Mbps. When I'm doing reverse BT (from the second router back to the 1st one), there is same problem but on the second direction. It is not depended on ...

OK, thanks for explanation.

Is any way, how to solve the problem? Or is it insoluble?

Hello, I want to make NAT from local to public IP 1:1 . But I have two internet gateways and it can happends, packet can go thru IGW1 to internet and packet can return thru IGW2. I made same IP FIREWALL NAT rules on both IGWs: ip firewall nat add chain=srcnat action=netmap to-addresses=185.160.20.17...

The way NAT works is that the router keeps a database of open sessions.

Yes, that's what I supposed ... but is there any way, how to switch off this behaviour? I just want NAT 1:1 ... change source or destination IP of packets exactly 1:1 and not check, if the session is opened or not.

I have LAN and 2 internet gateways - Mikrotiks CCR. One of the computers in LAN I want to make NAT 1:1 to public IP . The public IP is routed to IGW2, so all trafic from internet to the computer public IP comes through IGW2. But trafic FROM the computer can be sent by both IGWs. Everything works fin...

How to get ip broadcast address? :local brdcst [/ip address get [find interface="ether1"] broadcast] doesn't work ... is there any way, how to get it?

I want to use IP of interface in my script. I get IP address by command :global addr [/ip address get [find interface="bridge1"] address] If on the interface is just one IP, it works. But when on the interface are two or more IPs, it displays error message " invalid internal item numb...

Acually I solved that, but I don't like the solution so much ... My sollution: 1. Read all rules from ip/firewall/filter to PHP array. 2. Filter the array. 3. Remove from ip/firewall/filter .id's from the filtered array. It works, but there are 3 steps. Better would be 1 step - just "Remove fro...

Is planned to implement Ethernet Ring Protocol (G.8032) to RouterOS? It would be very helpfull.

Yes, usually upgrade works normally. I did upgrade already on a lot of Routeros. But this is the 1st time, when I have trouble with the upgrade. Can helps me please anybody from Mirkotik?

In legislation, it is mandatory to use DFS radar detection. But in real, it is unusefull. In case of Radar detection, the AP immediatelly disable transmission and change the channel. But then it waits at least 1minute, untill it starts transmission. After 1 minute time limit, the wireless started ag...

what about interference? make sure you use professional isolated pigtails, separate the antennas by proper distance, make sure you have an isolated outdoor box (metallic), see if you can't somehow isolate the cards between themselves (metallic sheet wrapped in plastic or something)?

We started to use MIMO technologies, based on Mikrotik and R52N cards, but I found strange thing: When there is just 1 card inside Mikrotik device (RB800+R52N), MIMO works correctly. Approximatelly 130Mbps (3km distance). But when I add more wireless cards inside this devices, MIMO has big troubles ...

I can't ping my wireless router or any address on the web. After I setup the bridge do I have to add a route to my gateway?

I solved that by folowing way: 1. I made backup of RouterOS (system backup save name="backup1") 2. I made new script called "restore", which contains one command: system backup load name="backup1" 3. I created scheduler (system/scheduler) for automatic start the "r...

In 2.9 RouterOS WinBox is always using this fixed port number (unless 2.8, where you could specify a port number to connect to). Hmmm ... that's bad.
