I fixed that by disabling offloading on that interface

	ethtool -K eth1 gro off
	ethtool --offload  eth0  rx off  tx off
	ethtool -K eth0 gso off

Nope.

Pretty simple

	INTERNET
	 |
	ADSL MODEM
	 |
	 | eth0
	SERVER
	 | eth1
	 |
	ETHERNET SWITCH
	 |
	 | eth0
	CLIENT

That's what I'm trying to do :-/

The config is pretty basic, admitting I cobbled it together piecemeal from posts,

cat /etc/dhcpd.conf
	authoritative;
	one-lease-per-client true;
	default-lease-time 14400;
	ddns-update-style none;
	ping-check true;
	shared-network "home-lan" {
	        subnet 10.16.10.0 netmask 255.255.255.0 {
	                range 10.16.10.2 10.16.10.64;
	                option subnet-mask 255.255.255.0;
	                option routers 10.16.10.1;
	                default-lease-time 14400;
	                max-lease-time 172800;
	                option domain-name "MYDOMAIN.net";
	                option domain-name-servers 10.16.10.1;
	        }
	        subnet 10.17.10.0 netmask 255.255.255.0 {
	                option subnet-mask 255.255.255.0;
	                option routers 10.17.10.1;
	        }
	}
	host tgdesktop.MYDOMAIN.net {
		hardware ethernet XX:XX:XX:XX:XX:XX;
		fixed-address 10.16.10.16,10.17.10.16;
	}
