Hi all I've built a setup very similar to: Connecting VMs Using Tunnels (Userspace) — Open vSwitch 3.1.90 documentation<https://docs.openvswitch.org/en/latest/howto/userspace-tunneling/>. Instead of a physical interface connected to the br-phy bridge, however, I'm using one side of a veth pair (gtpa). I'm receiving the GTP packets just fine on the br-phy bridge via this veth interface (gtpa). Thereafter I've got no idea where the packet goes or how to debug it.
I do see, however, the GTP packets have an invalid UDP checksum. I suspect it might be the reason the receiving GTP interface drops it. I tried setting 'options:csum=true' on the GTP interface but from the documentation it looks like it might not be supported and it did not help. Could this be the issue and what options do I have? Regards, Gerrie
