IPSEC from MT to Sophos UTM 2nd SA Kills 1st SA

Fri Jul 17, 2020 1:35 pm

Hello, i have configure a ipsec tunnel from MT to Sophos UTM.
1 tunnel works.
But if I activate a 2nd tunnel SA, the first SA no longer works.
Both connections are shown to me as established in Mikrotik.
The same setup works fine with a Draytek router.

The local Network in Sophos location for the 1. SA is 128.39.0.0/16 and the 2. SA is 10.39.54.0/24
The Mikrotik Network for the IPSEC Network is an vlan 46 in a bridge with Networkaddress 10.43.46.0/24

My second problem is that DHCP relay does not work either.
I checked on the Sophos with tcpdump and there is no DHCP packet arriving.
All other packets go through.

no one here who builds more than one SA from Mikrotik to another server?

Hi, the support helps me.
The solution for the problem with more then 1 SA is to change in the Policy on Tab Action the level from require to unique, see screenshot.

Hi,

I have the same problem. I can not connect the 2nd ikey2 VPN.

However, in IPSec Policy -> action tab - I do not have level. Only 3 items Action, IPsec Protocols & Proposal.

I'm on v6.45.6

Where it could be?
