DGND4000 will not accept zero octet in static ip

[markswift2003]

Hello,
I am replacing a long serving DG834G with a DGND4000.

I have a static IP address ending in 0 (zero) and the router will not accept this.

If I change the last octet to say a 1, it will accept this and report as connected, although this is obviously incorrect and therefore I have no Internet connection.

I understand that a last octet of 0 or 255 can be a broadcast address, but given my subnet mask, my IP address is legal.

Is this a firmware issue and if so is there an upgrade?

I am in the UK and my ISP is BE (part do O2, but soon to be Sky)

Regards
Mark

I agree, it's odd, but with the correct subnet mask (which obviously it has to be!) it's legal as a non-broadcast address, but the router won't take it.

Markswift2003,

May I ask the exact static IP Address, Subnet mask and Default Gateway you’re using so I can simulate your problem?

Is there a way that you can request your ISP to change your static IP? It’s weird that it’s taking in an ip address ending in zero because it is a network address. Theoretically, it shouldn’t really work. I’m surprised that your old router took it in without any problems to be honest.
