Need change router's IP - Calgarypuck Forums - The Unofficial Calgary Flames Fan Community

RedMileDJ · 05-10-2011, 01:16 AM

Ok, hopefully I am making sense here. I'll make this simple.

When I directly plug to my modem I get an IP of: XXX.XXX.XXX.blah, blah

and when I connect via my router it's different: xxx.blah, blah.

As per me looking up via http://whatismyipaddress.com/

Anyway, I need to know HOW to CHANGE the IP address being sent by my router.

It's a Linksys WRT160N

I have looked over the internet and the Linksys support sites. I can't get any clear answers.

Can anyone help?

Go into the router and setup MAC cloning and enter the MAC address of your computers network adapter and you should get the same results as plugging directly into the modem.

What are you trying to accomplish? The reason your IP is different connected to the modem vs the router is that the router is acting as a firewall, and you probably don't want to eliminate that.

He got his IP banned somewhere.

ok, just to understand what you are asking: Your external ip address (ie what whatismyipaddress.com says) is different if you plug your computer directly into the modem and if you plug your router into the modem?

And you want it to be different than it currently is when using the router, when using the router?

Cloning your MACaddress on your router using the method Raekwon said would work. I dont know the reasoning behind wanting it the same as your PC MAC though. If you just want it different, you could just change one number.

Where do I start?
IP address are assigned by a DHCP server running on the router from Shaw and by a DHCP server on your router. Shaw basically runs much bigger enterprise versions of the router you are using at home that does IP address assignment much like your home router

The address assigned to you from both DHCP servers will be MAC address or hardware ID dependent. The external IP that is used for internet that people external of your network (i.e. outside of your router space) is assigned to you from SHAW/Telus/Whatever ISP and will only change when a different piece of hardware (with a different MAC address) is pluged into it.

However, routers can change their ISP port (WAN) MAC addresses, so if you want a different IP all you need to do is change the one number at the end and make sure it doesn't conflict with anything else on your network (not very likely at all). All the computers on your home router reside within it's own sub network (or subnet) which the rest of the world can not see and has it's own set of addresses.

If you want the exact IP on your computer as your external, that's not possible unless you turn off the DHCP server on your router and make it go to switch/router mode. In essence this is shutting down your network and only relying on the address given to you by the ISP. But then only one computer will have internet within your home network.

Unless I completely misread your question and you only want to change the 192.168.X.XXX address range. That's something completely different.

That's not exactly what it is. Firewalls don't alter your IP address. IP address is different because of DHCP assignment.

Yeah, but based on the question I don't think you want to get into explaining NAT (and I'm guessing your previous response would have been way over their head).

I think Scott is correct in that we should find out why the question is being asked. It sounds like a misunderstanding and figuring that out is probably a good start.

Wrong.

Thank you everyone for the replies. All your information was useful and helped me change the IP. I have it changed now.

Much appreciated.

Cheers!

His IP address isn't different because of DHCP assignment, it's because with the router involved, there's two different networks in play. We don't actually know if he's using DHCP when connected to the router (but it's a reasonably safe assumption) based on the information provided.

I was emphasizing the firewall aspect of the router since it sounded like he was trying to get his PC to use a non-firewalled address, which is never a great idea for the average user.

Regardless, I'd love to know why he needs a new external IP address though, I bet its a good story.

it's different because shaw assigns the router MAC address a different ip as the computer MAC address... so assigning the router to clone the MAC address of the pc will simulate shaw giving out the IP to the computer mac address instead of the router (hence getting the IP assigned to the computer to the router)

You can't have the router give individual outside IP's to each computer on it, that was not the goal of what the user was trying to do.

Yeah, we're talking about two different things - I didn't initially notice that he was complaining about his external IP being different depending on the device connected - I thought he was complaining that his PC's IP address is different when sitting behind the router.

Do what it says above. Mac Address clone. change last number up or down one digit. Unplug your modem and router. I usually wait a few minutes. Plug in Modem. Then plug in router.

IP changed

Shazam · 05-12-2011, 04:59 PM

NAT, fer crying out loud.

fredr123 · 05-12-2011, 05:22 PM

Anyone else still curious for what purpose (nefarious or otherwise) you would need to change your IP address like this?

Champion · 05-12-2011, 06:05 PM

Besides a ban somewhere, maybe voting on a website?

Raekwon · 05-12-2011, 09:35 PM

I had to do this before because if I downloaded torrents then tried to use Ventrillo afterwards I got crazy 4k lag spikes so I did this trick and got the second IP shaw allows and all was good. So I would switch back and forth just for torrents.

DING, DING, DING! We have a winner.

It's something related to exactly this. Nothing bad. Wasn't banned or whatever.

I also got Shaw to give me the 2nd IP, so it's all good now.

I won't be commenting on this anymore. I have my problem solved. Thanks for everyone's help.

Cheers!
