Forwarding a port to 2 different lan addresses?

Energize · 16 Dec 2008 at 01:56

In our house there are two xbox 360 consoles which require port 3074 to be forwarded to them, if I create two firewall rules forwarding 3074 to each xbox will that cause a problem?

Yes, it won't work.

switch on upnp or change the port of one of the xboxs

do the above for free or if you want to spend money you can buy a second public IP and set up two NAT pools. depends how badly you want to keep the ports standard.

And whether your router/ISP will allow you to do this

Most ISPs have no issue with it, you can pick up a router for about £30 that'll do it... but as I said. It'll cost money as does the "proper" way to do most things.

Most consumer ISPs will not give you more than one static public IP.

Skidilliplop · 16 Dec 2008 at 15:41

Most of the Small offices I used to set up used multiple static IPs on Consumer providers. On Be they're £4 and you can have up to 6. With consumer ISPs they're not always contiguous blocks but Be/Sky/Demon/o2 for certain do as i've been party to such configs on those ISPs. There are probably more i'm sure.

tolien · 16 Dec 2008 at 15:52

The minimum option on Be is 8 IPs for £9.50, as far as I can see on the Be site. O2'll give you a single IP (for £5), but I've never heard of them offering subnets and again can't see anything on their site about it.

BT, VM, AOL/CPW, Tiscali definitely don't offer >1 public IP, if they offer one at all, and there's >90% of the consumer market.

BT do on their business services but not on their home tarrifs. There are lots of ISPs out there that do, they might not be the most popular ones but they are there. Most people just don't ask because they assume it'll be very expensive. If it's not on the websites you can usually pick up the phone and they'll do it for you.

My emphasis. Sure, Zen, AAISP, Enta, Plusnet (with justification) will give you a /29 but they are hardly mainstream consumer ISPs.

That is literally the most overkill thing ever for playing 2 xboxs!

wij · 17 Dec 2008 at 00:46

I dunno, if you use entanet and have a suitable router you can get a block of 8 IPs for free and its a pretty easy thing to set up.

It's not nearly as overkill or as costly as BUYING TWO Xboxes

If i was being overkill i'd have said Cisco 1700 + 2x ADSL WICs + additional line. With the added bonus of being able to aggregate the lines for non Xbox traffic.

Pick up a router that properly supports upnp, we have 3 360s and no problems playing Live on all 3 at the same time with just one public IP. The PS3 was more awkward, had to stick that in a DMZ to get it to play ball properly.

Energize · 17 Dec 2008 at 17:33

Yeah I've heard how bad the ps3 online system is, no one on campus can play online because the ***** at $ony won't give the university staff the ip information they need to get it working. I'll try upnp anyway.
