Network to Network IPsec IKEv2 VPN broken after upgrade to firmware 7.1.1 build 3775

I have been running 7.1.0 build 3433 since it was released. I use a Balance One Core to connect to several of my remote offices using Network to Network IPsec IKEv2 VPNs to WatchGuard 515s. It’s been working flawlessly until I upgraded to 7.1.1 build 3775. Now it’s stuck with "Initiating Connection to " status in the IPsec VPN Event Log and just spins on the Status > IPsec VPN page. My VPNs no longer work.

If I revert back to 7.1.0 build 3433 everything comes up fine. I know that WatchGuards aren’t supported devices but since I’ve had no issues prior I wondering if anyone else has seen this issue?

I’m thinking one of these fixes broke it for me. I’m hoping someone can confirm or deny they’re having similar issues.

ref 18637 - [IPsec] IPsec IKEv2 may stop connecting in rare conditions and cause high CPU load
ref 18938 - [IPsec] IPsec stops connecting after receiving “authentication failed” signal from remote peer.
ref 18660 - [IPsec] The IPsec VPN Pre-Shared Key is displayed incorrectly if underscore ‘_’ is used as part of the key. This is not affecting configuration file and just a display issue…


Please open a support ticket for support team to check.

We had just running a quick test for IKEv2 IPSEC connection and it working fine. The issue can be related to other thing that we need to investigate from the device.
