Need multiple internet IP's for 2 home pc's on router.

I have 2 computers in a network thru a router. Is there anyway I can
have seperate ips for each computer for the web, without using a proxy
server?

1. Use an NAT router. It's similar to a proxy server without all the
configuration exercises. All consumer wired and wireless routers
offer NAT. Since you didn't specify the make and model of the router,
I'll assume it's something rather special that uses a proxy server.

2. Have your ISP supply you with more than one IP address. No router
required. Just plug an ethernet hub or switch into your cable(?)
modem and each computer will have its own routeable IP address. Just
make sure the software firewall and security in each computer is
functional as you will not have the protection of the firewall in the
router. It's also highly likely that your existing unspecified router
will not work in this arrangement as most consumer routers cannot turn
off NAT.

What are you trying to accomplish and what do you have to work with?

If what you mean by "separate ips" is to have 2 public IP addresses that
the rest of the world sees, you would not get that by just having a proxy
server.

If what you mean by "separate ips" is to just have a couple IP addresses
that each computer can have, but have them be seen on the net under the
IP address your provider gives, which a proxy server could do, then NAT
is what you want (and should be part of any decent broardband router).

If you really do what each computer to show up places on the net as if
they really are from separate IP addresses, you will first need to get
2 IP address assignments from your provider and pass them through the
router unchanged (perhaps turn NAT off). The provider may charge you
an extra fee for the extra IP address; they have to pay for more bulk
IP allocations when they run out.

Well I have RoadRunner and I read that they only provide dynamic IP's,
so I guess that means they won't give me another? Plus I really not
interested in paying extra right now.

I use a Belkin router. What if I connected the other computer just
temporarily to a dial up modem and used one of RR's access #'s they
give out for when traveling? That would give me 2 different IP's
wouldn't it?

Thanks for trying to help me on this!

It's possible to get 2 or more dynamic IPs by registering 2 or more MAC
addresses with them, and somehow getting those MAC addresses exposed to
their DHCP server ... provided they are doing the DHCP thing. If they
are doing PPPoE, it would be a lot harder to set up and require many of
those hard steps on their end (e.g. it won't happen). Or it could be
done with a 2nd cable modem attached to a router that can do 2 PPPoE's
(no idea if the Belkin router can do that) or attached to a 2nd router.

The routing in RR's network would send all the traffic to the IP in the
dialup pool over to the dialup servers, and out to the 2nd computer on
the dialup line. You'd have to leave it there on dialup and get slow
dialup speeds. You'd have 2 IPs, but it would just be one computer
connected one way, and the other computer connected the other way.

To get the 2nd IP to come through the cable line, you'd have to somehow
get that IP into at least one routing table (and likely many tables) to
gateway it to the router they are using to serve the other end of PPPoE,
and in that router's routing table to gateway it to your 1st dynamic IP.
