How is you DHCP and addressing set up?

[admin@MikroTik] > ip address print
Flags: X - disabled, I - invalid, D - dynamic

ADDRESS NETWORK INTERFACE

0 D 192.168.10.17/20 192.168.0.0 WAN_1 PORT 1
1 D 192.168.10.75/20 192.168.0.0 PORT 2
2 192.168.10.1/20 192.168.0.0 PORT 2

I want to use Port 1 as a wan and take an external IP from my backend router use the Mikrotik as VPN SERVER!!!

NAME INTERFACE DHCP-SERVER LOCAL-ADDRESS

0 relay1 LOCAL SWITCH 192.168.1.240 192.168.10.75

[admin@MikroTik] /ip cloud> print

warning: DDNS server received request from IP 80.235.150.244 but
your local IP was 192.168.10.75; DDNS service might not
work.

I don’t see an address pool associated with your DHCP server. Pools are under /ip pool

If i got you right, the DCHP Server is your device and you are trying to get the dinamic ip on wan port of mikrotik.

You have to enable the interface under
/ip dhcp-client

Otherwise please send me a diagram an copy the result of /export.
