  • If you have a Linksys router...

    ...is there a way to greatly increase the DHCP lease time given to clients? The IP addresses on my network seem to change every few days which is getting annoying for port forwarding purposes. In fact, I just checked and the default DHCP lease time seems to only be one day.

    (don't want to use static IPs)

    Ive got a AG041.

    Client Lease Time: minutes (Range 1~10080)

    If you have the latest firmware and there's no options to do so then I guess not.

    1 Day is alot, I actually use 2 hours.

    Your only option is to use static IP's. Sadly Linksys don't have features to reserve an IP by Mac address's.

      I just looked through my router control panel and don't see anything. I use Static IPs on my network and don't allow DHCP requests at this time. Will probably have to allow DHCP when I get my XBOX360.

        It can't do static?

          I used to have a Linksys router. I remember having DHCP enabled but still specifying static IPs. Just set your DHCP range high, and then use low statics.

              I just gave up on it because apparently the longest lease is one week. I switched to static IPs which is an inconvenience but at least I can know the IPs won't change randomly on me.

              The one (only) good thing about my old D-Link router is that IPs effectively never changed with DHCP.

                Why not use a combination... You can use static IPs where you absolutely need forwarding and DHCP on other devices.

                  Is that legal? I thought if you have DHCP, it is a bad idea to force an IP address on some clients. I'm guessing that the DHCP server might accidently provide a lease for an IP that is alreay statically defined by some other client.

                    For example, use .2 through .50 for statics, and set your DHCP range to .51 through .100

                    edit - and assuming you are using NAT for an internal network, the only IP conflicts would be on the internal network.

                      Yeah it is legal... You can assign the range for your DHCP leases and use static IPs outside of that. You get 254 devices on the network. Hard to run out in the home environment.

                        I haven't used this specifically (I'm using HyperWRT), but I believe the Sveasoft version will give you static DHCP IPs based on MAC addresses.

                        (Though it only works with certain Linksys routers anyway.)
