Virtual private networks / Re: IPSec tunnel is up but no traffic (no bytes in or bytes out)
« on: Today at 05:33:16 pm »Its not a Phase 1 issue if Phase 1 is established and there is a Phase 2.
I expect there are no rules that allow traffic through the tunnel.
Just create a rule in Floating allowing any any on both Firewalls to troubleshoot, if this is not production yet.
Just a floating rule but still the connection is up but there is no traffic. I can't ping/ssh either anything on the other side.

Virtual private networks / Re: IPSec tunnel is up but no traffic (no bytes in or bytes out)
« on: Today at 05:22:09 pm »Seems to be a p1 issue.
You have to state the outside public IP as "My identifier" on both sites.
They are there already

Virtual private networks / Re: IPSec tunnel is up but no traffic (no bytes in or bytes out)
« on: Today at 03:36:24 pm »Did you create firewall rules that allow traffic?
If you mean the IPSec firewall rule, yes. I was following this article https://docs.opnsense.org/manual/how-tos/ipsec-s2s.html
Is there anything else to be allowed?

Virtual private networks / IPSec tunnel is up but no traffic (no bytes in or bytes out)
« on: Today at 01:54:04 pm »
I am testing opnsese on two VMs on Azure both live in two different virtual network and each has a single public ip address and a since nic as shown the below diagram.
I managed to get the S2S tunnel up but there is no traffic between the two opnsense servers.
I tried to ping a vm (or even the other opnsense) from opnsense1 server, but I get this message:
Same error I get when I try to ssh into the vm on the other side:
Any help is really appreciated.
