Out ISP has allocated us a /30 subnet so assuming 123.123.123.0/30 we have available 123.123.123.1 and 123.123.123.2

I do not want NAT so the router IP should be 123.123.123.1 with the first PC internally known as 123.123.123.2

Is this possible on the Vigor 28280n and if so what should be set.

I can ask the ISP for larger block if necessary but it feels like this should be simple.

Thanks
Gary

Additional Inforation. Our ISP is allocatng us a fixed IP which would be the 123.123.123.1 address. Does this conflict with the same IP on the 2nd WAN Interface which ue to the small subnet is set to be the same IP of 123.23.123.1

I need the internl PC to be 123.123.123.2

Thanks
Gary

With the 2820 you can have the same fixed IP as the 2nd subnet IP, so you should still be able to do it
