[SOLVED] 19.7.4: Rebooting the switch - OPNsense looses WAN connection/routing

[rainerle]

Hi,

after rebooting the switch attached to the MASTER OPNsense the firewall loses its WAN connection/routing, but does not failover to the BACKUP.

Only after executing menu option 11 (Reload all services) WAN is working again.

ixl0 is a access port attached on that rebooted switch, ixl1 is the LACP lagg port attached to that same switch. The second switch stays alive and takes over operation during the reboot of switch 1. WAN connection fails as soon as the rebooted switch comes up again.

No idea how to go from here...

So taking the Ports down on the firewall down one by one -> Logfile:

All good, no problems with the WAN connection on the firewall. Must be something else, maybe the length of the downtime or both interfaces coming down and up at the same time.

[rainerle]

To prepare for suricata I changed to configuration of the network interfaces:

• Got rid of LACP lagg devices
• ixl0 - LAN - admin_port
• ixl1 - WAN - uplink interface (the switchport is assigned to the proper VLAN)
• ixl2 - VLANs for all other OPT interfaces
• ixl3 - pfSync interface directly attached to the backup OPNsense

Since getting rid of the LACP lagg devices the reboot of the switch attached to the master OPNsense does work nicely: The CARPs fail over to the backup OPNsense, as soon as the master's switch comes up again the master OPNsense takes over.
