Good morning, I created a site to site IKEv2 tunnel between a chr mijrotik and a sophos firewall. the link was established correctly as was phase2.
I encounter this problem:
- if I ping from sophos to mikrotik I don't ping.
- if I ping from Mikrotik to Sophos the ping works.
- if after pinging from the mikrotik to the sophos I try to ping from the sophos again to the mikrotik everything works. this is until the reboot.

I don't know where to turn. in Nat I have the accept rules of the remote subnet and the firewall is all turned off

The two resources I found are:

Good luck, I use wireguard and it works well!!
