Hello guys,
I've a Cable Internet connection and my ISP offers me 5 public IP addresses, but the IPs are offered by DHCP and they're not 100% fixed IP (because they change if I don't use it for more than 3 days).
The problem is that the mac is associated to a MAC address, and when I try to add other IP to the router, the mikrotik, only allow me to use only ONE IP address, how can I add my other 4 ip address to my mikrotik IP Pool?

Thanks,

Best regards

Any idea? or the post is not clear? (because english isn't my primary language).
Thanks

Anyone know the answer?
Thanks,

Best regards

I'm not asking for the DHCP server, I need to add multiple IPs from a DHCP Server (act as a DHCP clients) using multiple MACs.

What he wants to do is obtain 5 IP addresses via the dhcp-client and then push 4 of those down to devices behind his Mikrotik.

The only thing I can think of is a dhcp-relay. I don't know of a way to automate that in Mikrotik.
