Using static and dynamic IPs on network

[MrMaster]

I've been running a home network for many years already but I never really messed around with static and dynamic IP's mixed on my network. I have an Orinoco router with several wireless and wired connections.

I want to keep everyone on the DHCP except my main computer. This is because I run emule and am sick and tired of changing my open ports when the IP changes. My router assigns ranges in the 192.168.253.x area. So I put in 192.168.253.5 as my static IP with a gateway being the router's IP address, 192.168.253.1.

Emule connects and actually works but nothing else will. Anyone want to help me out?

Not sure about your router, but you may be able to reserve DHCP addresses. You tell it the MAC address, and the IP to reserver, and it does the rest.

Are you saying then to not use an IP address in the DHCP range for my static IP?

Yes, that is the way it should work. If DHCP is 192.168.0.1 to 192.168.0.10 the static (example) shoudd be 192.168.0.33

I'm saying that you can configure your router's DHCP settings so that it will reserve one of the DHCP addresses for your emule machine. That way it the emule system can be setup to get a dynamic IP, but it will always be the same. 🙂


Or you could just pick a true static IP outside of your dhcp range, as JackMDS suggested. I prefer the reserved IP route though personally.

Well, since I'm bored at work, here's a quick guide on how to setup your network to get the static IP route to work, in case you don't want to do the reserved IP thing.

Setup your router's DHCP settings to give out IP addresses in the range of 192.168.253.2 - 192.168.253.50 for example. I doubt you have that many machines, but whatever. Now you can configure your emule system to have a static IP address of anything above 192.168.253.50, just make sure you set the gateway to be 192.168.253.1 (the router), and the subnet mask to be 255.255.255.0.

The reason you have to limit your dhcp scope is because if you give your emule system a static IP that is within the dhcp range, there is a chance that eventually your router will give out the same IP to some other system, and then you are screwed...

I think I only post at AT when I am at work. 🙂

So if I have my computer setup right now with a static which is in the same range as the DHCP numbers, this would explain why the rest of my internet stuff isn't working?

I know my subnet mask is correct and like I said before my gateway is already at the 192.168.253.1.

If your static IP is conflicting with another system, one, the other, or both could stop working.

So I tried the suggestions given. First, there is no option in my router to put in MAC addresses. That leaves me with the static and dynamic IP situation.

I picked an IP that was out of my dhcp range (the range was already set to 2-10) I picked 25. Whatever I tried I still only got emule to work and nothing else. Something tells me that you have to be all DHCP or all static on the network if using only 1 router or maybe just this 1 router.

The hosts behind the router should be fine as long as there is not an IP conflict (two hosts trying the same IP address). Keep trying.
