So I have a TrueNAS Scale, latest version, up and running with the following network setup.
10Gb interface on an access port with br0 configured and an ip in the 192.168.1.0/24 subnet
10Gb interface on a trunk port with only vlan 20 assigned, and an IP in the 172.18.10.0/24 range
Issue I am having is that I cannot ping the vlan 20 IP from my firewall unless I manually add an arp entry. Doing a tcpdump on interface vlan20, I can see the arp request come from the firewall and the arp reply go back out, but it never reaches the firewall. Like wise, if I ping from the TrueNAS server, I see the arp request go out, but the firewall never receives it.
Is this an issue by having the dual 10Gb interface setup?
Here is what the tcpdump on vlan20 looks like. There is only the TrueNAS and firewall on this vlan
root@truenas[~]# tcpdump -i vlan20
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on vlan20, link-type EN10MB (Ethernet), snapshot length 262144 bytes
