DHCP RELAY ISSUE

RouterOS General
1

Hello,

I have central router with dhcp server, and two other routers configured as relays,

one is working fine and gives leases to clients from central router,

second one makes requests but does not receive replies from central server.

In torch on central router I see UDP src 68 to dest 67 coming from working dhcp relay router
and udp src 67 dest67 from non-working one, and central does not reply him.
172.22.14.4 is relay router and on the right column there are IP-s of central.

Mikrotik, Can you help to solve this issue?

Central router CCR1016, relay-s are rb2011 , routeros version 6.7 on central and 6.2 on relays, it did the same with version 5.x
P.S I have several IPs on interface on central, I tried on all of them, As I remember on V5 I was able to make it work on certain Ip addresses on Central

Thanks

Is Mikrotik doing anything about the issue I described, I am waiting for it more then a week already

is dhcp-server configured to accept packets from relay? Please see wiki.mikrotik.com on how to use dhcp-relay.

yes it’s configured properly, it works on interface which has 1 ip address, but when interface has several ip addresses it does not work,

I need solution for that

Janisk,

Is Mikrotik working about this issue? No one answers on email support@mikrotik.com

Not good to have such poor support

Is this issue fixed in the latest release?

I cant find anything in the release notes about it.

It seems to be fixed in 6.15.

I do not know, anybody from Mikrotik confirm, I have already changed to one ip per interface scheme
