Router for multiple static IPs
- Thread starter CrispyXUK
- Start date
When you say "support" do you want to put your devices directly on the web? If so you can do that with something like a cheap DG834 or if you want to to use NAT/PAT then probably want to look at cisco kit - Can pick up Cisco 837's for reasonable money these days
Thanks, we have a netgear 3500 but can't work out how to configure multiple static IPs on it, as you said, we need to expose a few web servers to the web and currently can't do it without this ****ty BT router.
Any idea what we're doing wrong? There seems to be no option to configure multiple IPs on the netgear.

OK, some more info would be helpful wouldn't it? 
BT Have given me the following details;
Network address; 1.1.1.2
router/hub address; 1.1.1.8
subnet mask address: 255.255.255.248
Do I ignore the network address? router/hub is this the "Internet IP Address" I assume? The only page to enter a subnet mask is on the LAN page.
I have a few netgear VPN firewalls to assign addresses for networks as well.
Thanks

Should be as simple as setting the LAN side of the router up with the info for the subnet that BT have assigned you and then from memory under one of the menus there is an option to disable NAT.
This will basically mean you're passing real world addresses to anything behind the router, so that would sort out your servers, and then you would need to put a simple ethernet router off the Netgear to NAT one of those IP's for all your other clients (assuming that you have a lot more hosts than real IP addresses).
Personally I think for a business environment that is a bit of a kludge and you should look at proper kit as I have no idea what sort of security (if any) the Netgear offers when you disable NAT.

Thanks my man, so my understanding is;
ASDL Page
Get automatically from ISP
LAN Page
IP: 1.1.1.8
subnet: 255.255.255.248
Then assign public IPs to the VPN firewalls via than LAN page?
We do have a cisco modem/router/firewall, but we can't get ADSL to connect on it

Not sure what you're getting at with the firewalls, you would set up their WAN interfaces to use one of the public IP's that BT have given you (fwiw that subnet looks very odd to me).
What model Cisco is it, I could probably knock you out a config to have it working for you, probably a lot better than the Netgear...
Give this a go, I'd recommend doing a sh run and backing up whatever config is already there first as I've done this from memory but it should be ok.
You'll need to fill in usernames and passwords for the router itself and also for the Dialer interface for the ADSL line.
VLAN1 interface needs to be given the IP address that BT have said to use for the router.
You should then be able to statically configure the IP address of a machine plugged into one of the Cisco's lan ports and get internet access with a real IP address.

Er, how do I get this config on the thing?
Serial connection to the routers console, you should have got a blue DB9 to RJ45 type cable with the router.
I wouldn't recommend this if you're that unsure of what you're doing.
BTW I'd be very curious to know if that subnet BT have assigned you actually works, just its listed as part of a much larger network assigned to APNIC...
It does, we're using it currently with the BT router supplied.
Previously when configuring the cisco we did it via a web interface. The thing has never worked so we're not that worried about it, we connect via hyper terminal I presume?
