I'm not sure where this should go. But I am having trouble with my dedicated server and some IP addresses that I have been assigned.

basically, I have a dedicated server that is all working, I have a block of 5 IP addresses that all work fine.

Now I have ordered another block of IP addresses (/28).
I have been advised by the hosting provider that these addresses are not routed and don't have a gateway assigned to them and that I have to do this my self.

Could someone advise how I should be configuring these addresses?
Do I need PFsense set up in a VM to act as a router?

Thanks in advance
