OK. I have tried everything in my power to try and fix the double NAT complications with my modem and router setup. But no more. I am going to buy a new modem or modem & router. But, which do you people recommend I do?


Replace the modem, which is from around 2001, or replace the modem and router and get the modem and router in one system?


(also, recommendations on good modems/modem-routers are welcome)


Thanks in advance

In your case just get an all in one unit, semi complex networking setup doesn't appear to be your fotre.

Dynalink RTA1025WE is highly recommended.

Why not just plug the adsl router into the lan of your wireless router and only have one nat?

A lot of wifi routers will also operate in a "bridge" mode, meaning that they act as dump pipes between the two networks.  I've got my Linksys configured this way.  It no longer does it's own NAT or DHCP.


Broadcasts are still filtered (I think) so some things don't work between the wired/wireless networks (bonjour), but it gets rid of the nastiest bits of the second NAT.

That would be acting as an accesspoint, not a bridge.

Bridging is usually over WDS between 2 seperate networks with multiple mac addresses on each, and certainly does pass broadcast traffic. Its client mode that is the one that breaks broadcast stuff because they usually do mac spoofing and DHCP mangling to get multiple mac addresses on their ethernet port showing as a single mac address to the accesspoint they are associated with.

Here are his two previous threads where we tried to help him set-up his two devices in WAN bypass mode (ie: use DCHP/NAT on the modem and use the wireless router as just an AP):

Here's his previous thread where he asked the same question as this thread:
http://www.geekzone.co.nz/foru...

Unless he can find someone to help him in person I reckon in this case he'd be best off just getting a simple to use/setup all in one device like the Dynalink RTA1025WE and selling his existing modem and wireless router on trademe, would probably work out even $ wise and be less angst.

Ah well, seems he has already had plenty of good advice so yeah, an all in one idiotbox would be the logical choice.

You will need to turn off the DHCP on the LAN settings if you do that, since the 2nd router becomes just like a hub.

Well yeah, goes without saying that you would do that.

Step one - buy a draytek vigor 120 ADSL 2+ modem. plug it in, turn it on and set it to PPPoA passthrough.

Step two - buy a linksys WRT54GL (note the 'L').

Plug the two boxes together and enjoy.

Well it's a LITTLE more complicated than that, but not too much. Single NAT goodness.

Unfortunatly the linksys is only G so has a very hard time working when there are N networks operating nearby.

Anyone know a similar router that can do openwrt etc and has decent N support in it? And doesnt cost the earth.

The OP didn't state he/she required 'N'. In the case of SOHO routers, newer isn't necessarily better - particulaly depending on application. In fact I was surprised to see brand new WRT54GL's in Dick Smith this weekend - must be a demand for the ol' girls!

If 'N' is a requirement, then there are some linksys 'N' models which can be flashed with open-source - see here:

Note: take care which revision / version you are contemplating purchasing, as different versions of the same model may NOT be open firmware capable.

The OP hasn't replied since the 1st of Feb,  thread would have automatically been locked due to inactivity if webwat hadn't brought it back from the dead for no apparent reason Wink
