Issue detail:
Firewall to firewall RED tunnels (RED site to site) with force TLS 1.2 config enabled not working on v20 EAP1 build #195. Even re-creating the tunnels does NOT solve the issue.
Work around:
Please disable Force TLS 1.2 from Web admin console on RED Server side as shown in the below image.
Resolution:
This issue is being worked upon under the ticket NC-125221. The issue is specific to early access release of v20; and we are working to resolve it in the next release.
It is recommended to apply the workaround before upgrading to v20 EAP1 to eliminate any disruption to RED site to site tunnels.
Thank you twister5800 for reporting this issue in the early access program. We value your contribution.
Sincerely,
Sophos Firewall Product Team
