VPN IPsec tunnel keeps disconnecting

[newcmelgar]

Hi guys,

I have 3 sites (A, B and C). Here is the setup:

• Site A pfsense: 10.75.24.0/24
• Site B pfsense: 10.10.0.0/24
• Site C peplink: 10.3.4.0/24

Site A-B are connected with site-to-site using OpenVPN where Site B is the Server and A the client.

Site B-C are connected with IPsec. I have created 2 tunnels to reach the 10.10.0.0 and 10.75.24.0 networks from the 10.3.40.0

So the problem I have is that the 10.10.0.0 keeps alive always and the 10.75.24.0 disconnects from no use. To bring it back to live I have to send a ping request from 10.75.24.0 over to 10.3.40.0 and then all works. But if I pink from 10.3.40.0 to 10.75.24.0 it doesn't work to bring it back to life.

Any clues how I can get this working so that this tunnel doesn't disconnect?

Thanks,

Carlos
