DHCP Issues in Syslog....time to go Static?


Recommended Posts

Every 12 hours there is an entry in my syslogs like below.    My networking skills are so-so.  I am running a custom firmware ( Tomato-MLPPP ) and the DHCP range is set as:  192.168.1.100 - 192.168.1.149

 

Would the best option be to just statically assign my server to 192.168.1.67 and 255.255.255.0 for subnet and 192.168.1.1 for gateway and DNS server?

I generally set to static as well so that I always know what the server is. You can try to set the lease time on the router for longer and that may help if you want to leave it as DHCP.

 

Also someone correct me if I'm wrong but the easiest is to have you DNS address the same as your router (which having a quick flash over seems to be 192.168.1.254)

I have the same issue but I'm running Pfsense :

If I know my router hands out DHCP from 192.168.1.100 - 192.168.1.149 , is it even necessary to reserve IP's by MAC address or is the easiest way to be just selecting Static IP's from 192.168.1.150 and higher?

 

My router IP is 192.168.1.1 , so I would set that as my gateway and dns I believe.

As long as your router has a subnet mask of 255.255.255.0 you can use any address in 192.168.1.2 - 192.168.1.254. Except ones that are currently assigned by your router. If you assign one in 192.168.1.100 - 192.168.1.149 your router will not use it. You can be certain that your not using an assigned address by not using 192.168.1.100 - 192.168.1.149. 255.255.255.0 should be the default subnet mask in your router. So, yes.

 

Yes, use 192.168.1.1 as gateway and dns. Also add 192.168.1.1 as the first ntp server if your router proxies ntp.

 

I found it slightly easier to configure a static address by reserving it in my router and leaving unRaid set to auto except for the ntp addition.
