IPSec VPN Issues (after upgrade to 7.0.1-5018)
We have a TZ470 with two IPSec IKEv2 Tunnel running to two different 3rd-Party firewalls. We have had both tunnels running with the 7.0.1-R1456 firmware. After the upgrade to 7.0.1 both tunnels are not working anymore. We get the errors below. In the package monitor, I can also see the TZ respond with a message "no proposal chosen". All the things we see indicate a mismatch of phase 1 proposals, which makes no sense to us.
What we find strange is that we did not change anything at the config on any side of a tunnel. we also deleted the policies and re-created them.
