Leasing IPs from the DCHP

[Zucarita9000]

Can I lease an IP from my DHCP server (a Linksys BEFSR41) for 6 months? I mean, If I type in 259,200 seconds, will the unit support it?

I think there is a cap on the Linksys DHCP time (and its really low like only a day). Also you could just give yourself a static IP since it uses a private IP address. For example I use 192.168.1.234/24 and put the DNS info in from the router's info page.

Yeah.... I would probably end up doing that. Thanks

it should, but the real question is why you want to do that?

if you want both static and dhcp on your network, just use IP addys outside of the DHCP pool for those boxes that you want to assign an number manually.

The DHCP server should have a max lease time it'll allow (and it's definately more than a day in the DHCP spec, I think we use 7 days at work) so it all depends on your DHCP server. There's really no reason though, you'll renew your lease before it expires as long as the client is on anyway.

the RFC doesn't have a limit. You can try setting a lease time of 0 which means "never"

However, on a Lynksys router, 0 means one day.

I still can't fathom why you'd need a lease that long though.

I know, I was just messing around with the settings. I can easily use a static IP for that machine, that's all.
It's because the PC is a notebook that uses a dynamic IP in two different networks (the office and home) and I didn't want to change the settings (static for the office, dynamic for home or viceversa) everytime I switched environments.

Oh, I forgot. In the office I used port forwarding in order to be able to connect to the PC via pcAnywhere. Port forwarding needs a static IP, or at least I need to know what IP that machine will have in order to forward the ports to it. If I choose to lease an IP for say, six months, I know exactly waht IP that machine will use.

If you know anyway to reserve an IP based on a MAC address, please tell me.

BTW, I'm using a Linksys BEFSR41.-

I believe a lot of Linksys products use Linux internally, you might be able to 'break' in and configure dhcpd manually.

Well, I don't know anything about Linux. I would probably mess everything up and void the unit's warranty.
