Using ReadyNas 102 with dynamic IP

I've just switched across to the NBN and, unfortunately, the modem supplied does not allow you to fix IP addresses. So I have this issue where the IP address changes and my backups and mapping of the...

    Thanks Stephen and Sandshark................

     

    So I've changed my IP start and end addresses on the modem to 2 and 150 respectively and assigned a static IP address outside of that range for the NAS.  So far, so good. I'll keep watch to see what eventuates.

     

    The Technicolor 784 modem for which you (Stephen) supplied the link to the manual is a completely different setup and interface to the 789 unfortunately. So it definitely seems the case that the 789 has no capability to fix IP addresses. I've hunted through the user interface everywhere and there appears nothing remotely connected to fixing IP addresses.

     

    I'll monitor the changes over the coming days and, if it all works out ok, then I'll accept the advice as a solution.

     

    Thanks heaps again for your help and advice.

     

    Cheers..............Mike

The modem is a Technicolor TG789vac v2 HP and I can't seem to find any online manual for it explaining anything about fixing an IP address.

 

 

This guide is for a TG784, but is might also apply to the TG789:  http://www.khimhoe.net/2015/05/31/how-to-assign-static-ip-in-technicolor-tg784n-v3-using-dhcp/

 

It shows you how to find a check-box item for "Always use the same IP address".  If you can find that check-box, it's best to use that control to lock in the RN102's address.

 As for the static IP I've set on the ReadyNas, I've searched the modem setting and think I've found the IP range you mention.  Under 'Local Network' it has the following -

 

DHCP Server ON
Network address
xxx.xxx.1.0
DHCP Start address
xxx.xxx.1.2
DHCP End address
xxx.xxx.1.254

 

Correct, this is the DHCP range.  The max value is 255, and that is reserved for IP broadcast.

 

So if you want to configure a static address manually in the NAS, you change the DHCP end address to something smaller - for instance xxx.xxx.1.99

 

The use xxx.xxx.1.100 for the ReadyNAS.
