VyOS to pfSense - OSPF - Wiregaurd tunnels

pwabrat

I am attempting to replace a VyOS device with pfSense version 2.7.2 for a branch location.

Below is the current VyOS configuration for the branch device.

If I remove the ip ospf area 0.0.0.0 setting from the interface configuration, the connection works, but I still encounter some challenges. The main issue is that OSPF Network is now deprecated, and we cannot rely on manual configurations in frr.conf because they often get overwritten.

Additionally, the ip prefix-list Extended_LAN 10.168.110.0/24 10 permit configuration is sometimes overwritten.

Another challenge is that I am at the spoke/branch location and do not have access to the hub location device. It seems that pfSense relies heavily on GUI-based configuration.

Could you please suggest the exact configuration steps I need to follow to successfully connect the branch device to the network without requiring manual intervention? Thank you.

Below are current config in GUI.

@pwabrat Sorry for the delayed reply,

the issue resolved by Route Redistribution in pfSense Kernel Routes of "Extended_LAN"

Thank you for the support.
