I am using some local ip ranges in my lan and to various VPNS I am connected to. Lets say they are:
Now it turns out that our ISP started to use one of these ranges. I hade troubles with StrongSwan going down repeatedly for days and could not figure it out.
Now to the question. Can I block off 10.0.0.0/8, 22.214.171.124/16 so that no traffic from these IPs can reach my router from wan? What is the correct way to deal with this?
Apart from the VPNs I have a standard setup with zones where LAN can reach WAN.
