IPSec with Google Cloud

Fri May 26, 2023 3:08 pm

Hi,

We have a VPN IPSec from our Mikrotik and Google Cloud and it is working very well. But every time the connection negotiates we see almost 200 lines in log registry like this:

2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated
2023-05-23 03:39:14 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated
2023-05-23 03:39:17 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated
2023-05-23 03:39:20 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated
2023-05-23 03:39:23 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated

But after a while, it reconnects correctly. I have been reading a lot in other posts like the link below, but still having the issue.
viewtopic.php?t=184015

Just before the line "error no policy found/generated" it shows 0.0.0.0/0 but I don't know where this 0.0.0.0/0 comes from:
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec processing payload: TS_I
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec 0.0.0.0/0
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec processing payload: TS_R
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec 0.0.0.0/0
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec candidate selectors: 0.0.0.0/0 <=> 0.0.0.0/0
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec searching for policy for selector: 0.0.0.0/0 <=> 0.0.0.0/0
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec policy not found
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec,error no policy found/generated
2023-05-23 03:39:12 Local7.Debug 192.168.1.1 ipsec adding notify: TS_UNACCEPTABLE

On Google Cloud side It is quite "black hole" because there is a wizard where you cannot modify any setting.

Any help would be appreciated!
Thank you very much
Josep
