Configuring GRE-tunnel for additional IP's from extraip.com (speed limit?!!)

[bitfinity-nl]

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 ;)
