VPN IPSEC with BGP Routing

[ugo.neiva]

Hello everyone,

I am setting up a Opnsense appliance and using some common configurations that i use on other vendors to connect to the Company i work for.

I've configured a VPN IPSEC between an Opnsense and a Mikrotik Routerboard, and the connection is established normally, phase 1 and 2. For local and remote networks, i've created 2 loopback interfaces with the ips 10.8.1.1/32 and 10.8.1.2/32 and i've tested that they ping each other normally.

After that, i've configured with FRR a bgp session between these two IPs in order to receive the company prefixes, and for them to receive my office network prefix. The session is established and i see an exchange of Prefixes, but, a i can't access any of the networks i received and the company also cannot ping any of my devices.

I've doubts if i am making something wrong with the VPN configurations or the bgp configuration. Can someone shed a light on this mistery?
