I currently have a single ip address going through my netgear router to my server, which is windows server 2008. I want to add 2 new statip ip address from my cable internet service provider. My question is how I can get all 3 ip addresses to the one server? Do I need a special router? Or can I do it on the server?

Currently, the single ip address is configured on the netgear router, but it does not have an option for more than one on the netgear.

Thank you.

You would need a router that can handle multiple interfaces, something like a Watchgaurd Edge.

You need two things: -

1. you need to put your router into bridge mode.  This allows it to make a connection to the internet and it will pass all traffic to your network
2. Get yourself a firewall that can accept the three IP addresses you have allocated to you.

I cannot stress strongly enough how important it is for you to have a firewall to protect your network.  DO NOT RELY ON YOUR WINDOWS 2008 SERVER TO DO THIS.

A good firewall is Astaro (www.astaro.com) and it's free.

You should NOT use bridge mode in to your server this is not a good option. You should purchase a router that can handle multiple IP addresses.

ProtechCT = can you recommend a specific Watchgaurd router? I looked at their website and was not sure which one supported multiple ips

jakethecatuk= are you saying I can use my current netgear router in bridge mode and then handle the ips in windows server?

You can put a router into bridge mode darius provided it's behind a firewall (as per my original post)

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

mlg101 - don't rely on your Windows server to protect you - it won't!!!!!

 Either get a decent router/firewall like the Watchguards (or similar) or use your existing router and get a decent firewall to protect your network.

Part of my post is missing I must have deleted on accident. Bridge mode is fine as long as you are going to another device like a firewall.

So again, does any watchgaurd product support multiple IPs?

And if I do bridge mode with a separate firewall, can windows server handle the IPs separately?

Thanks for all your help guys!

Give them a call and tell them what you want to do and they can recommend one that is right for your situation.

Before I answer mlg101 - what budget do you have for this as this will depend on the answer.

Also, what netgear router is it?

Its a Netgear RP614 v4, and I would rather not spend any money on this, but if I have to spend money, 300 bucks or so would be as much as I could do right now.

OK - well that will rule out a Watchguard as they aren't that cheap.

You could look at what's available second hand on e-bay.  Juniper SG5GT is a good alternative.

If you have a spare PC lying around that is working - Astaro firewall (link above) is free for home use.  All you would need for your old PC would be another NIC.

If you are on cable, I'm guessing you have an RJ45 cable that goes into your Netgear.  If that's the case, you can plug that cable straight into your firewall and then go from your firewall to your LAN and use the Netgear as a switch.

Does this make sense?
