hello
dhcrelay does not work with this scenario
A B
--------------- -----------------
-----------
| dhcp server | | dhcrelay |
|client |
| FreeBSD 11.0 |<--------->| FreeBSD 11.0 |<-------------->|windows|
-------------------- em7 em0-------------- em1

----------------------- DHCP server configuration ---
/usr/local/sbin/dhcpd -user dhcpd -group dhcpd -chroot /var/dhcpd -cf
/etc/dhcpd.conf -pf /var/run/dhcpd.pid em7
dnsmasq is enable
dhcpd.conf:
option domain-name "localdomain";
option ldap-server code 95 = text;
option domain-search-list code 119 = text;
option arch code 93 = unsigned integer 16; # RFC4578

max-lease-time 86400;
log-facility local7;
one-lease-per-client true;
deny duplicates;
ping-check true;
update-conflict-detection false;

subnet 100.100.10.0 netmask 255.255.255.0 {
pool {
range 100.100.10.1 100.100.10.50;
}
option routers 100.100.10.10;
option domain-name-servers 100.100.10.10;
}
--------------------------------------------------------
on device B:
dhcrelay -i em0 -i em1 100.100.10.10
em1:192.168.1.10/24
em0:100.100.10.100
--------------------------------------------------------
when i test this scenario DHCP packets arrive to DHCP server but they can
not return to device B where my dhcrelay is running.
if i connect device C to DHCP server directly ,It takes ip fast so i think
my DHCP server config is working fine
What caused the problem?
What's wrong here??
