IPSec S2S Tunnel problem

[herrnic]

For a few days now I've been racking my brains over an ipsec tunnel connection that doesn't really want to work.

Phase 1 and phase 2 are established but unfortunately I can't reach the other side.

I hope someone here has an idea and can help.

Version: OPNSENSE 21.1.6

Here are the data from ipsec statusall:

Code: [Select]

root@OPNsenseVF:~ # ipsec statusall

Normally I should be able to reach 139.1.2.3 via telnet when the connection is established.


I notice this message in the log files.

Code: [Select]

charon[16026] 12[KNL] <con1|1> querying policy 213.1.2.3/32 === 139.1.2.3/32 out failed, not found
I cannot interpret these correctly.
Is it just a routing problem?

Here is netstat:

Code: [Select]

root@OPNsenseVF:~ # netstat -rn

Does anyone have any ideas?

I am grateful for any inspiration.

I have no access to the other side.
IP addresses have been changed by me and are only an example.

Phase 1 entries are correct.
Phase 2 don´t match with the other side.

[herrnic]

but in the status overview the status is "installed routed".
If phase 2 did not match, this would not be possible.

[atom]

Have you marked "install policy" in phase 1 "advanced options" ?

[herrnic]

Install policy is marked

[atom]

You're default router is 192.168.10.2 and not WAN (192.168.10.198), correct ?
Do you have a network plan ?

[herrnic]

192.168.10.2 is default WAN Gateway

I do not have a network plan with me at the moment.
