I need some help with an adjustment to my setup. Basically my ISP gives me 5 public IP addresses to use. At the moment my ISP line is connecting directly into ethernet 1 of the RB450G, with all kinds of rules setup in place.
But I now need to take advantage of the switch options on the RB450G.
So there is what I’m trying to do:
ISP > Switch (RB450G) ethernet 3 > ethernet 1=same as before & ethernet 5=new public ip
So I’m trying to create a switch on the RB450G for the ethernet ports 1&5, by using ethernet 3 and the ISP trunk. Now if I use a standard switch on my current setup, it works fine. But I’d like to use the inbuilt function.
If you are using a switch now, why not just assign all public ips to ether1? You will probably need to modify the rule in “/ip firewall nat” to action=src-nat instead of action=masquerade.
Thanks for your reply, for my ISP, the look at the MAC address for each IP request. In order to get a static IP you have to have unique MAc address.
So for that reason, I must using a switch and then allow the individual ports to use their mac addresses. I mean any bog standard switch can be used - simple connect ISP ethernet cable to say port 1, and then each server to another one of the ports on the switch and its done.
