Hello ,
i Need your help in the following Network:
(in Attachment)
i need to build IPSec Tunnel Site to Site between Mikrotik and Sophos that Host PC with IP 192.168.17.100 can reach server with IP 192.168.1.100
i have get Phase 1 established but i cant get phase 2 whatever Config i use on both sides,
any one have done this before can help me with config on both side
can i build IPSec if mikrotik behind a router and his wan interface is nated do i need to make any port forwarding for 500 and 4500 and esp because i tryed it also with no success.
thank you guys

no one??

Hi,

I'm sorry, but you didn't provide any useful information about cour config to help you.
Please post your config and exclude an sensitive data.

What's in the logs of your MikroTik? Add a log rule in "System" -> "Loggin" with "debug" and "ipsec" to see what is happening.

Next thing, depending on your FritzBox model, your FritzBox does IPSec too. So there might be in conflicting setup.
But this is just a guess.

Ape

Hi,

thank you for providing the additional information.
Unfortunatelly, I don't understand what I see as the IP adresses in your config are other IP adresses than in your diagram.

From the UTM's log you provided, I can see a peer ID of "192.168.178.84" is used. This looks like an IP from the LAN of the FritzBox. In the diagram, your MikroTik router is 192.168.178.100. Furthermore, your IPsec policy does not match the nets in the diagram.

If phase 1 establishes correctly, then you need to look at the policies to find the issue.

Hi Ape,
vielen dank für Ihre nachricht , ich have Ihre Blog gesehen das Sie auch in Deutschland sind,
also IP in diagrams sind einfach ein Beispiel die richtige IPs sind wie im logs .
Phase 1 ist established aber leider sehe ich nicht unter Installed SaS . exchange mode muss main sein IKe2 wurde auch Phase 1 nicht laufen aber mikrotik sagt das main ist unsichere und solte Certificate dafür nutze.
any Idea?

HI to All ,i got this to work after few Hours of Testing , if someone need to establish the same Ipsec between UTM Sophos and MIkrotik just reply here and i will help you out with the configuration.
wish you all a Merry Christmas and Happy New Year

i established a ipsec connection in almost similar way but cant rout trafic trough ipsec conection all it gose trough the wan only

Hello, would you be so kind and help me with Ipsec between Mikrotik and Sophos UTM? I have exactly same problem as you had. Only Phase1 and no phase2
