Unicast traffic not forwarded on links

Hello Guys,

I had EVE-NG running on Esxi6.0(L5630,96G_RAM) for a few months. A few days ago I started having problems. Suddenly unicast traffic between emulated devices is not forwarded anymore. Broadcast and Unicast are making all the way across the links, in fact ARP resolution works on the devices, but as soon I'll attempt a ping I don't get the echo request on the other side. I have done a tcpdump on the bridge interface and I can see all the unicast packets there but the problem is that they are not forwarded/replicated to the bridged interfaces.
No changes before the issue started.
Anyone ever had the same problem? Did you manage to fix it?

Thanks,
Alessandro

Ok I have found the issue and fixed it, for some reasons iptables was dropping the packets ":FORWARD DROP", fixed it by "iptables -P FORWARD ACCEPT" :roll:
