Openvpn site to site NAT PORTS

[Julien]

Hi Guys,
We have 4 Offices using opnsense
2 are using a hardware and 2 using VM on a ESXI. the VM offices are behind a NAT, before the opnsense there is a ISP Model.
the two offices that are using the hardware they can connect to each others fine no issue.
the two behind the NAT used to work before but lately they stops working after the update tp 17.7_2.
the log doesn't shows way.
I've created and deleted the tunnel like 100 time but it did not comes up.
Can someone advise is this a routing issue or something on 17.7_2 ?

Thank you

Hi,

well - some more details would be helpful...!

We have a TAP bridged to local lan on opnSense - opnSense is behind a router which is connected to ISP - on the router portforwarding is set for the vpn connection. That's all.

Cheers, Stephan

This exactly what we had and its been working for over a months until we updated both boxes.
on the VPN log there is nothing really that would explain the reason why.

the tunnel has been created and deleted many times without a success.
