Configure router (with DDNS) behind a primary router
Hi,
here's my situation:
I've a modem/router provided by my ISP (this router cannot be changed since it provides ISP specific services). This modem/router has a LAN IP 192.168.1.1, a mask 255.255.255.0 and 2 DNS 195.238.2.21/22 provided by the ISP. DHCP is enabled (range is 192.168.1.2 - 192.168.1.255).
Unfortunately, this modem/router does not have Dynamic DNS (DDNS) feature, and I realy need this since I've to access my network from outside. I already have an account on DynDNS and a host is ready to be updated.
I solution is to connect a PC (always up and running) on the network and install a DynDNS client updating the WAN IP for the specific DynDNS host --> not really a good solution if we don't need a PC running 24h/24.
Another solution is to add a router behind the acual router, offering DDNS functionnalities --> I've bough a NetGear WNDR3700 (great Wifi range, speed and many features including DDNS).
My question is how to configure (IPs, DHCP on/off...) this second router in order to:
- Provide a wireless access to the LAN and to Internet
- Update my WAN IP on DynDNS
The WNDR3700 has a RJ45 WAN port and 4 LAN ports --> googling, I don't have to use the WAN port, is it correct? But will DDNS work finding the WAN IP of the first router ???
Many thanks!

Re-read your question--
You seem to have not bought it. This model only supports dyndns.org what about other DDNS service providers like no-ip.com

You will need to use the WAN port of the second router.
>>>But will DDNS work finding the WAN IP of the first router ???<<<
If there is no configuration issues you will be able to get through the router 1.
You must also ensure that the 2nd router does not broadcast the 192.168.1.XXX network
To make minimal changes to the network I will configure the 2nd Router to broadcast IPs in 10.0.0.XXX/255.255.225.0

Hi,
thanks guys. Here're my tests using your tips:
Router 1 (DSL Model provided by the ISP):
IP: 192.168.1.1
Mask: 255.255.255.0
DHCP: Enabled from 192.168.1.11 --> 192.168.1.50
IPs 192.168.1.2 --> 192.168.1.10 are reserved for static assignments (2nd router, Media Center, Home automation gateway...)
Router 2 (NetGear WNDR3700):
IP: 192.168.1.2
Mask: 255.255.255.0
Gateway: 192.168.1.1
WAN IP: 192.168.1.3 + 2 DNS provided by the ISP
DHCP: Enabled from 192.168.1.51 --> 192.168.1.100
I've tried using a separate IP range for the 2nd router (10.0.0.x) as suggested by asidu, but apparently when a PC is connected to the 2nd router he gets an IP 10.0.0.x (which is normal), but I cannot communicate with other devices having an IP 192.168.1.x... The idea is to have all the devices (connected on both routers) connected in a single network.
Another issue with the WNDR3700 is that when he detects a possible conflict with another network (and apparently it does here), he changes the whole IP range used --> he decides to use 172.16.0.x for instance, to avoid any conflit. This can be problematic, and I've already not found how the disable this "automatic network conflicts detection".
last but not least, I've a poor range with the WNDR3700 (this is not the topic of the initial question, but if someone has the same problem..) which normally is very good he his category (true dual band with 8 antennas and Netgear RangeMax technology). Indoor I've problems at 35-40 feet (12 m), and the house is 70 feet (25 m) long.
Thanks for your support!

Also interesting:
I've a switch connected to a LAN port of the router 1 (ISP).
Both WAN port and 1 LAN port (4 available) are connected to the switch.

For your last concern :
If you get that set-up working fine you could run a lan wire to another location from your Router 1 and place the Router 2 another location to get better coverage. Lan cable should not go beyond 100m.

Thank your for the points and hope your network is running according to your need.

Yes, the 2 routers seem working perfectly now. Thanks.
You can ask your ISP for an account und pw.
If your ISP is not cooperative look for any other cable or dsl ISP.
