A Day in the Life of Just Another IT Guy » L2TP with IPSec on Mikrotik RoutersOS

Hopefully Apple gets the Tethering option fixed - and Mikrotik gets ROS update going with L2TP with ipSEC fixed. I allowed Firewall and i have no idea. Debug crypto ikev1 127 is empty but then i ping from asa-sb 192. Apple is aware of the issue an currently evaluating it. To disable IpSec, registry modifications are required. I need an idea how to go on. The network icon near your time display in the right hand system tray. Success was only partial. Enter the username you want to use to logon to your L2TP VPN server Password: set your password here make sure it is good and strong Service: change to L2TP Profile: change to the profile you made earlier or leave at default-encryption Note:default encryption does not work with IPhone 4 as it needs the Use Encryption to be set to default under Protocols like we mentioned earlier. The Phase2 is about l2tp ipsec mikrotik настройка " IPsec Proposal " on the Mikrotik Side, so be sure the Auth end Encyption Algorithms checked in winbox are allowed on the ASA. Both local networks are routed through L2TP client, thus they are not in the same broadcast domain. Then we tried it on iOS 9. Click the network Icon again in your system tray and now this time choose connect and you should be connected. Everything is fine from iOS, but when I try to connect from macOS device I always get an error l2tp ipsec mikrotik настройка IKEv1 peer config for x. If a packet is bigger than tunnel MTU, it will be split into multiple packets, allowing full size IP or Ethernet packets to be sent over the tunnel. If configured properly what works in iOS 9 should work fine in iOS 10. Max packet size that L2TP interface will be able to send without packet fragmentation. PPTP is getting a Bad Rap for being unsecure so I implemented SSTP with an SSL Certificate for my Mikrotik Router. The purpose of this protocol is to allow the Layer 2 and PPP endpoints to reside on different devices interconnected by a packet-switched network. Google is your best friend!!! Anyways, on l2tp ipsec mikrotik настройка my blog on Mikrotik and L2TP. Now we get to the good stuff.

Manual:Interface/L2TP - MikroTik Wiki

Note: in both cases PPP users must be configured properly - static entries do not replace PPP configuration. It works for Windows and iOS, but not for MacOS. Here is my script for securing the L2TP server to IPSec clients only. SETTING UP IPSEC: L2TP does not need IPSec but L2TP by itself does NOT provide any encryption as it is a Tunneling Protocol. If the Mikrotik have a static IP try create a Tunnel Group with IP, if not use a tunnel group l2tp ipsec mikrotik настройка FQDN. If the server still does not receive any response from the client, then the client will be disconnected after 5 seconds. But it works on the iphones perfectly. It can be daunting but I will step you through step by step to get this working. On my side wrong PFS Group was the issue. I allowed Firewall and i l2tp ipsec mikrotik настройка no idea. David, that you think about do no use a script to check the sa-src-address with the DHCP assigned IP? I rarely need it over a cell connection, but it would be nice to have it as a backup. Locate new L2TP connection and right click on it Choose Properties from the pop up menu Click on the General TAB Make sure hostname or IP is correct Click the Security TAB Type of VPN: choose Layer 2 Tunneling …. The Phase2 is about the " IPsec Proposal " on the Mikrotik Side, so be sure the Auth end Encyption Algorithms checked in winbox are allowed on the ASA. I highly recommend using only mschap2. How did you made ipsec up? Example Mikrotik Router IPs Interface : ether1-gateway — 1. I am still l2tp ipsec mikrotik настройка 789 error. Seams to me that all of the config scenarios found on wiki or forum work for iOS, but neither one of them works with macOS. Now things get Interesting. The bridge should either have an administratively set MAC address or an Ethernet-like interface in it, as PPP links do not have MAC addresses. A reboot usually cleared what was wrong and then the phone would connect to the Mikrotik again. Maximum packet size that can be received on the link. On my side wrong PFS Group was the issue. I need an idea how to go on. I will try your metod.

Default UDP stream timeout is 3 minutes. I rarely need it over a cell connection, but it would be nice to have it as a backup. Maximum packet size that can be received on the link. If configured properly what works in iOS 9 should work fine in iOS 10. Also checking the firewall I noticed after some times it did not even connect anymore and the Counters on IP Firewall Filters did not increment. Here is my script for securing the L2TP server to IPSec clients only. Enter the username you want to use to logon to your L2TP VPN server Password: l2tp ipsec mikrotik настройка your password here make sure it is good and strong Service: change to L2TP Profile: change to the profile you made earlier or leave at default-encryption Note:default encryption does not work with IPhone 4 as it needs the Use Encryption to be set to default under Protocols like we mentioned earlier. Hopefully Apple gets the Tethering option fixed - and Mikrotik gets ROS update going with L2TP with ipSEC fixed. Multilink PPP MP is supported in order to provide MRRU the ability to transmit full-sized 1500 and larger packets and bridging over PPP links using Bridge Control Protocol BCP that allows to send raw Ethernet frames over PPP links. On iOS you sometimes need to delete and re-add the profile even if you have all setting entered correctly. The network icon near your time l2tp ipsec mikrotik настройка in the right hand system tray. Note: By default Windows sets up L2TP with IPsec. Try, change on both devices PFS from "group5" to "group2"2. On my side wrong PFS Group was the issue. A reboot usually cleared what was wrong and then the phone would connect to the Mikrotik again. For IPhone 4 you also only need mschap2 set here. Maybe i forgot something on the config or i had to change something on the RB3011? The Phase2 is about the " IPsec Proposal " on the Mikrotik Side, so be sure the Auth end Encyption Algorithms checked in winbox are allowed on the ASA. Standards: RFC 2661 L2TP is a secure tunnel protocol for transporting IP traffic using PPP. On my side wrong PFS Group was the issue. If the server still does not l2tp ipsec mikrotik настройка any response from the client, then the client will be disconnected after 5 seconds. Also maybe just change the " PFS Group " from "modp1023" default to "none" and clear the "Installed SAs" on the Mikrotik. I tried to open some websites too but none of them worked.

I got some questions about how to configure Mikrotik to act as L2TP Server with IPsec encryption for mobile clients. I know this is not exactly in the line of.

NOTE: Sometimes I had to reboot my IPhone if it was not connecting. L2TP traffic uses UDP protocol for both control and data packets. This page has been accessed 370,020 times. Carlos de Armas 1 month 4 weeks ago Discussion Help!? Algorithm: sha 1 Encr. However a good name will help you remember what it is for later on when you have a whole lot of VPN connections made. This way it is possible to setup bridging without EoIP. My ASA is 8. On my side wrong PFS Group was the issue. Max packet size that L2TP interface will be able to send without packet fragmentation. This example demonstrates how to set up L2TP client with username "l2tp-hm", password "123" and server 10. Apple is aware of the issue l2tp ipsec mikrotik настройка currently evaluating it. UDP port 1701 is used only for link establishment, further traffic is using any available UDP port which may or may not be 1701. I tried to open some websites too but none of them worked. It may also be useful to use L2TP just as any other tunneling protocol with or without encryption. If selected, then route with gateway address from 10. Both local networks are routed through L2TP client, thus they are not in the same broadcast domain. A reboot usually cleared what was wrong and then the phone would l2tp ipsec mikrotik настройка to the Mikrotik again. L2TP encapsulates PPP in virtual lines that run over IP, Frame Relay and other protocols that are not currently supported by MikroTik RouterOS. I want to use Shrewsoft or another VPN client. In my L2TP Profile under the Protocols TAB I changed Use Encryption to default instead of required and then my IPhone worked as well as windows 7 Pro. However, I still have problems with the connection. I allowed Firewall and i have no idea. Note: By default Windows sets up L2TP with IPsec.
