Re: L2TP (IPSec) connection fails from MikroTik Client to MikroTik Server

Ok, i had to do some deeper troubleshooting. I've enabled "ipsed,!debug" logging on my MT and found this inside logs: faata, NO-PROPOSAL-CHOSEN notify message, phase1 should be deleted. So I've checked debug logs on a laptop to see the negotiation and found that connection established using 3des-aes...

Re: L2TP (IPSec) connection fails from MikroTik Client to MikroTik Server

OK But what exactly with IPSec? The key set on mikrotik device is exactly the same as the one I've set on laptop. All client configuration: - Server IP - Username - Password - IPSec Key Are consistent between L2TP config on laptop and L2TP-Client config on my MikroTik. So what exactly is the problem...

Re: L2TP (IPSec) connection fails from MikroTik Client to MikroTik Server

I actually asked for a log couple of days ago when i noticed this issue on MT. This is on the other side, i will have to type it in manually since i got a screenshot instead of paste. ipsec, error <src ip addr> failed to pre-process ph2 packet ipsec, error <src ip addr> peer sent packet for dead pha...

Re: L2TP (IPSec) connection fails from MikroTik Client to MikroTik Server

I'm not sure about the settings on server since i do not have access to it. But if i remove IPSec key from VPN Config on a laptop, it will fail connection. So it has to be set to required.

Re: L2TP (IPSec) connection fails from MikroTik Client to MikroTik Server

Ensure the server side has firewall open for IPSEC-ESP. As you are going through NAT it may be that NAT-T isn't working correctly. But i can connect from laptop from same place just fine. So it should be ok. Right? Setup is like this MikroTik VPN SERVER < - - - - - - - < INTERNET > - - - - - - - < ...

Re: hAP ac^2 Suddenly stopped reaching gateway periodically

OK So I've figured something new out. It would seem that everything was working fine up until today. Today i reverted back to stable release (6.45.5) and issue started happening again. But this time, it would seem to be related to my Laptop only! Not sure why. I got my Raspberry Pi (connected via 5G...

Re: hAP ac^2 Suddenly stopped reaching gateway periodically

Thanks for your reply. I was using ROS 6.45.3 until i upgraded to 6.46beta34. Seems MAYBE more stable this was. For example yesterday after update it continued to do the same thing, but after an hour it stabilized and it doesn't seem to be happening again. Would you advise to downgrade to 6.44? I've...

Re: hAP ac^2 Suddenly stopped reaching gateway periodically

Happened again so here is what I've noticed. Not only that MikroTIk will stop pinging the gateway, but devices on LAN will also stop pinging MikroTik. For example, if i connect Laptop via WiFi to MikroTik SSID (or my ISP router wireless AP) at the same time when MikroTik stops seeing the gateway, la...

Re: hAP AC2 as main router over bridge setup

Unfortunately, due to financial sit here in Serbia, i could barely afford this one :) This one costs 100 EUR here, btw. So i will barely be able to afford another one and avoid my wife killing me in the process. That's why i wanted to see if i could get this one working this way. But it's definitely...

hAP ac^2 Suddenly stopped reaching gateway periodically

Hello everyone. So I've had hAP ac2 for a week or so, and everything was working perfectly fine ! I'm very much satisfied with this device. However, today something strange happened. Suddenly, MikroTik was unable to ping gateway. I have a router that is connected to my ISP via coaxial cable. On my I...

Re: RB750 Bricked after updating to 6.45.2 [SOLVED]

So, I've managed to solve this, don't know how to be honest. Since netinstall would not cooperate with my seem to be bricked device, and since I've noticed that device is eager to boot from network, I've setup my own TFTP server and pushed openwrt firmware to it! RB750 booted openwrt but didn't flas...

I knew some mangle needed to be done i just can't figure out what! I've performed something, so far seems alright ! However, when connection is established it's TERRIBLY slow when compared to previous setup when i was just using NAT. I've done some troubleshooting and it seems to be slow because of ...
