Mx 250 wan ip address

[shlomoi]

Hi,

I need your help, we recently purchased a new MX 250 for our new branch, we purchased from our ISP a number of public IP addresses 5.29.128.0/28
We use the address 5.29.128.2/30 on the MX and the DG is 5.29.128.1/30.

 I want to use the rest of the addresses I have from the provider in  my LAN, can these addresses be used within one of our MS switches.

Can I configure port routed on the switch or on the MX ports.

Thanks

Could you use 1:1  nat?  That would be the easiest way

I'm not sure you are describing the address range properly.  If you have 5.29.128.0/28 from the ISP and they are using 5.29.128.1 on their equipment as the gateway then it is part of the /28 network.

You can use 5.29.128.2 as the interface IP on the MX, but you would be best using a /28 subnet.  You can then use the other IP addresses in the range via 1:1 NAT as @ww suggests.
