Multiple Static IP

If you have to ask ....

Given how much information is missing in this question, you likely need to find someone local to you to help.

Bridged or routed?

How big a block?

How many computers get exposed directly vs 1 to 1 NAT vs 1 to many NAT?

And very likely someone needs you to answer the "why" of the last question to make sure you aren't making a big mistake.

Figure $150 or so for a decent router. (But I'm making a LOT of assumptions here based on lack of real knowledge.) More depending on features. Less if you don't really need "several Static IP addresses".
