I have a PFSense setup where i have a Failover set up, However i notice some strange behaviour.
I have 3 interfaces.
The Wan is connected to the internet of course.
The LAN is my local network
My house is next to the family bussiness wich has a whole separate network and internet connection. There is a connection to this network as a 3th interface with the purpose of having access to the security camera system without having to have it go over the internet.
This network is also setup as a Tier 2 gateway in case my internet goes down.
This last week i seem to have lost any internet access on my WAN, All my traffic is routed over the backup line, However, my VPN and HAproxy still fuction propperly and i have access to my network over these. These connect to my WAN IP wich i thought was down.
My WAN is connecting with a PPPOE connection provided by my isp and gets a public ip
The company network provides me with a private IP for the incoming connection.
when i ping 188.8.131.52 from my WAN i get 100% packets failed,
however when i ping my WAN public ip adress from outside the network i do get a reply,
When i access a port forwarded to an internal adress from the outside the connection works. I can see the traffic go in and back out.
At this point I don’t know where to look anymore. Any ideas are welcome.
