Hi,
You will find the answer in the second paragraph of the description for
the dhcrelay(8) manpage.
It's fantastic that we don't even need the internet to find the answer.
Happy reading.

hi eveyone
if i have a dhcp server in subnet A connected to interface em0 (lan) and
subnet B connected to interface iwn0 (wireless zone) on the router
with dhcrelay -i em0 running on the router should the wireless subnet be
able to get its dhcp address from the dhcp server on the lan ?
Hi Riccardo,
dhrelay only operates on a single interface, so you're not missing anything
there.
Can you show me the ps output for the dhcrelay processes you start? The rcctl
commands you show below don't include the rcctl start dhcrelay and
dhcrelay_second bits.

Hi,
Just upgraded a set of my firewalls that also do dhcrelay to -current.
The program stopped working ok. Some dhcp requests where being forwarded some
not.
tcpdump was showing the request on internal interface but I couldn't see the
request being forwarded on the external interface

hi
is there an possiblity to forward dhcp request from
an rdomain X to the runing dhcp server in rdomain 0 ?
if i start the dhcrelay -i em1 192.168.131.250,
i see that he forward the request but never reach the server.
the clients in rdoamin 0 works with the dhcp server.

Hi,
I am running an openbsd router attached to several vlans. On one of them
there is running a box with an isc-dhcp server.
For one of the vlans I have started a dhcrelay to forward the dhcp
broadcasts of the respective subnet to the server
dhcrelay -i vlan5 172.16.1.4
This is working

to make dhcpd listen on lo0, and then have dhcrelay listen on enc0 and relay
to lo0. (dhcpd runs on same machine)
