Netduma R2 won't assign ip to my Linksys router (DHCP)

[Chaiyoabc]

Hi, 

I have been having major issue here in my netduma R2. 

This is my current setting. 

It's my ISP modem+router --> Netduma R1 using PPPOE --> Linksys WRT54GL via DHCP.

Thie recent issue I have had with was that my R2 wouldn't give or assign ip to my linksys which I find it strange because it was normal yesterday. 

So I tried with R1 and it worked!! so I'm sure issue must be from R2. So any idea how to fix this?

Perhaps the DHCP lease renewed and then another device took the IP and it got confused. Assign the Linksys a reserved IP in R2 Settings, also change DHCP Lease hours to 168 as well and then reboot the Linksys, does that work?

no @Netduma Fraser it's not working

On the Linksys does it say that it is getting a WAN IP at all?

I solved it now 

it has something to do with this

Okay yeah it doesn't make sense to use the router IP as the DNS in this scenario. I assume after you removed this it worked?

No, I removed it = won't work. have to stay like this

That is very odd, what is upstream of the R2? Is it a pure modem or modem/router? If you put another DNS in does it work?
