Hi chaps

I've added a 10Gbe card to my proxmox machine, as well as one to my xigmanas. The network config is as follows:

NAS
LAGG0 (teamed 2 x 1gbit), 192.168.0.100
OPT_1 (10gb card) 192.168.20.1/24, no gateway

Proxmox
enp6s0 -> vmbr0 192.168.0.15/24, gateway 192.168.0.1
ens6f0 (10gb card interface 0) 192.168.20.2/24, no gateway
ens6f1 (10gb card interface 1, inactive)

At the moment, traffic only seems to flow one way, when I test with iperf3.

When xigmanas is the listener, we get no traffic in:

NAS side

When I reverse the roles, this happens:

What am I doing wrong here?
 
Looks like _not_ setting the MTU does not set it to default value on Xigmanas. Now working fine..
