Hi All,
I am not quite sure where to put this, but I think for some users this should be helpful.
I needed some extra IPv4-addresses, I got them from extraip.com so you have to configure them via a GRE-tunnel.
The procedure to get it to work is:
- Create a GRE-Tunnel
- Assign the GRE-device to an interface
- Enable the interface
- Configure the gateway
- Configure the public IP's via Virtual IP's
- Configure the firewall rules
- Configure outbound NAT
So I have OPNsense installed in a Proxmox VM (VIRTIO) and I have 1Gbit/s connection, the default WAN connection reaches the 1Gbit/s but via de GRE-tunnel it's not more than 30Mbit/s no matter what I do.
So before going further investigate, is there a limit in OPNsense (or BSD) with GRE-tunnels?
* I will update the documentation along the way ;)
