OpenVPN tap - endpoint issue

[mdrapeau]

Hello everyone,

I built a VPN on tap mode between my two sites which have the same subnet:

I don't understand why only the endpoint of the site A is unreachable from my site B while the entrypoint of the site A is accessible.

Firewall rules allow everything in the OpenVPN interface and LAN interface too.

I don't know how to fix this issue.

Thanks!

Mathieu

Finally I found the issue, it was the promiscuous mode which was disabled on the OVH network interface of the site A.
