I guess that not every RTL8168H/8111H has problems; there was an earlier bug report about RTL8168H/8111H at https://marc.info/?l=openbsd-bugs&m=159403196706770&w=2 The rest of this mail only shows my dhcpd configuration, and might be useless, because you have a working dhcpd on another interface. I connected an Ethernet wire from "pehcehwahn" re0 to "maryland" gem0 and ran dhcpd re0. The wire was loose (ifconfig re0 said, "status: no carrier"), but it began to work after I fixed the wire. The link is 100baseTX because my gem(4) can't gigabit. --George re0 at pci4 dev 0 function 0 "Realtek 8168" rev 0x15: RTL8168H/8111H (0x5400), msi, address 00:d8:61:ca:7a:49 rgephy0 at re0 phy 7: RTL8251 PHY, rev. 0 pehcehwahn$ ifconfig re0 re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 lladdr 00:d8:61:ca:7a:49 index 1 priority 0 llprio 3 media: Ethernet autoselect (100baseTX full-duplex) status: active inet 172.27.0.1 netmask 0xffffff00 broadcast 172.27.0.255 pehcehwahn$ cat /etc/hostname.re0 inet 172.27.0.1 255.255.255.0 pehcehwahn$ cat /etc/dhcpd.conf subnet 172.27.0.0 netmask 255.255.255.0 { option routers 172.27.0.1; option domain-name-servers 172.27.0.1; range 172.27.0.32 172.27.0.127; ... # other hosts host maryland { hardware ethernet 00:0a:95:89:5b:f2; fixed-address 172.27.0.5; option root-path "/home/maryland/root"; } } maryland$ ifconfig gem0 gem0: flags=248843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,AUTOCONF6TEMP,AUTOCONF6> mtu 1500 lladdr 00:0a:95:89:5b:f2 index 2 priority 0 llprio 3 groups: netboot egress media: Ethernet autoselect (100baseTX full-duplex) status: active inet6 fe80::20a:95ff:fe89:5bf2%gem0 prefixlen 64 scopeid 0x2 inet 172.27.0.5 netmask 0xffffff00 broadcast 172.27.0.255 maryland$ cat /etc/hostname.gem0 dhcp inet6 autoconf
