RED Device Boot Looping after Router Upgrade

Updated 2 routers that have RED 15 devices attached. Updated to the latest firmware.

Both Red Devices are now on 1 minute connect/disconnect loops. 4 hours on phone support with Sophos to get no answers.

Anyone else experiencing this? I now have a site that's 3 hours away that's dead in the water because Sophos can't figure it out.

I also upgraded an XG125 to an XG136 and all VPN's failed. I had to delete all VPN's across 6 devices and manually rebuild them in order for them to work. Another 5 hours of Sophos Support leading to no resolution.

Hello there,

Thank you for contacting the Sophos Community.

We have no reports about issues with VPNs after upgrading that I am aware of.

To which Firewall Version did you upgrade to?

18.5 MR2 had an issue with RED causing massive network traffic but that is solved on 18.5 MR3 released today.

Can you share your Case ID?

This is what happened:

Had an XG125. Backed up the config and applied it to an XG136 Router for the upgrade. Booted the 136 and only 2 of the 5 VPN's worked. Rebooted the 136 to see if it was a fluke for the other 3 VPNs not connecting. Upon rebooting I lost all connectivity between the 5 VPN's. I was able to activate them, but they would not connect the two networks programmed in to the vpn.

This is what I had to do in order to resolve this issue:

1. Delete ALL VPN'S and RULES associated with the VPNs on the 136

2. Delete all VPN's and RULES on all 5 routers that we had VPNs created to

3. Rebuild VPN's with new PSK's and have the vpn auto-create the firewall rule without saving on activation

4. Rebuilid the VPN on the remote target with the vpn auto-creating the VPN rule and not activating on save

5. Reboot the remote Router I am attempting to connect to

6. Activate the VPN on Both the 136 and my target router for the VPN. Once both sides were activated, the tunnel connected.

7. Rinse/repeat for all 5 VPN connections I was working on restoring.

As far as the RED Devices go, I had to enable the Unified RED Firmware option under System Services. Once I enabled this and saved it, I had to reboot the target RED Device and it connected without issue.

Big shout out to the Sophos Support tech "NItesh" as he figured out the Unified firmware option. A level 2 engineer chalked it up to a failed RED Device and wanted me to RMA it.
