Various problems with High Availability (problems with OpenVPN and SquidProxy)

[Jeromeb]

Good morning all. I have set up an OpnSense machine which works fine. Proxy service enabled which works perfectly and OpenVPN which works perfectly.

I decided to set up a second OpnSense machine for failover.
I have done all the procedure to set up the high availability. The high availability works very well, I have my master and my client etc ...
Since the implementation of the high availability, I have encountered very frequent disconnection problems on OpenVPN. I ended up fixing the problem by forcing the MTU to 1400. I didn't have this problem before setting up the high availability.
And more boring, impossible to browse the internet through the proxy. I tried both on the IP lan and the IP v-lan, the proxy no longer plays its role. Without proxy just with gateway i can go to internet, but i want to use the proxy service.

Do you have any idea on this?

Thank you in advance.

I answer to myself and it can be useful to someone. Having no answer, I started from scratch, clean reinstallation and followed the procedure for the installation of the high availability. The virtual IP for the LAN did not work as a gateway on the network stations and in the proxy config on the browsers until the restart of the 2 opnsense. There everything is well functional. My mistake was initially to cloning the first opnsense machine to make second : that is not a good thing. The second machine must be set up from from scratch.
