Router set up for server problems

[Homebuilder]

Hi, I have a linksys, older model router.

Before with sage 2.0 you only had to list the name of the server, now the client software defaults to the name plus IP address.

My problem is when the power goes off or for some other reason the local ip changes. The clients can not auto log on since the IP changed.

Similar problem with the placeshifter. I open the ports on lets say 192.168.1.102 and then the server changes to 192.168.1.105 and now plce shifter doesnt work.


Any way to to force a linksys router to always have the computer named DVR be 192.168.1.101 ???

Newer routers do it? older ones?

This is becoming more of a pain since I really like placeshifter.


Thanks,
Neal

you need to make sure that the fixed ip addresses you use for your pcs are not in the same range as the DHCP server uses in the linksys router config. My linksys router itself defaults to 192.168.1.1, and then it assigns DHCP addresses starting at 192.168.1.100 (this is configurable). So you've got between 192.168.1.2 and 192.168.1.99 to allocate fixed IPs. I use fixed IPs for all my Pcs, DHCP would only be necessary for a pc you move around to other networks, like a laptop.

Thanks!

Those step by steps would be appreciated....I think I found where I do it, but they have properties for subnet and gateway... so do not want to mess with it without further direction.

Side note, today my old linksys router broke down.. or was hacked to oblivion. Have a different one now.

Thanks again, look forward to those instructions..

If you have a new router, there should be a place on its DHCP page to assign fixed IP addresses to specific MAC addresses (netcard IDs). This is preferable to configuring static IPs on the server itself because you get all the benefits of DHCP (such as autoconfiguration of gateway and DNS addresses) plus a fixed IP address.

For step-by-step instructions, consult your router's manual.

Nope, new router doesnt do that... Which it did. EVen updated the firmware.

I just removed 192.168.1.1 - 192.168.1.25 from the DHCP scope. This give me 25 addresses to statically assign and the rest for DHCP clients.

I always thought that you could assign static IP's (which is done on each computer) even if it's in the DHCP range? My network is setup this way. The Linksys should know that computer X is static by the routing table, and just skips that IP when assigning DHCP addresses.

No, the DHCP server could assign the address to another computer and cause a IP address conflict. That's why most DHCP servers allow you to define the scope.

The routing table is for figuring out which port to forward packets to so that they get to their destination.

Ah...mine's setup incorrectly, but the static IP's are at the very end of the DHCP range and never get doled out. I'll fix that, thanks.
