Title: Simple VXLAN issues
Post by: vitafit on September 12, 2022, 04:47:04 PM
So I setup two OPNsense-VMs, both on the same Hypervisor with only one NIC each, bridged towards my actually LAN. I wanted to try VXLAN between the two VMs, just as a proof of concept. Unfortunately ICMP over the VXLAN is not working / maybe the whole tunnel is not working?

This is how my config looks:

I also created Floating and Interface-Rules allowing All-Traffic, disabled automatic NAT-Rule creation and reduced the VXLAN-MTU to 1450. Both VMs can reach each other on the LAN-Interface, therefore establishing the VXLAN-Tunnel should be possible:

I tried using Multicast (239.1.1.1) and / or setting the interface, nothing changes. I simply can't ping / send & rcv ICMP-Packets between 192.168.60.1 and 192.168.60.2.

Is there even a way to check the current VXLAN-Status? I could not spot any log-file containg anything regarding VXLAN. Most likely I am doing something fundamentally wrong here, please bring me up so speed.

Kind regards
