DHCP Error

I keep getting this error:

nov/22/2013 01:29:20 dhcp,critical,error dhcp-client on ether1-gateway lost IP add
ress 172.251.52.151 - received NAK from dhcp server 192.168.100.1

Does anyone know what this means?

Could this have anything to do with Safari not loading pages and having errors?

Thanks.

Do you have a 192.168.100.1 address or network assigned on your router? It sounds like you have 2 dhcp servers on the ether1-gateway interface.

What ip does that interface have when it is working? Is it the 172.251.52.x address?

It happen when the dhcp server assign other ip address for your wan interface.

So it’s normal, and nothing I should be concerned about?

If that affects your internet connection it is not normal. Normally, your dhcp server will issue ips in the same range as your old ip. It is very odd that you get the 172.251.52.151 ip from the dhcp server at 192.168.100.1 or vice versa.

That’s the way the modem works. If the isp has an ip address it sends that. If the iso loses the address or drops it, then the modem switches to a private ip address.
