WRT320N randomises destination IP adress !

Hi,

I have a huge trouble with my brand new WRT320N.

 

I have seted-up my router with an ADSL modem in PPPoE connected to their WAN interface.

 

Several time per hours, when my computer (or other connected to the router) send an  HTTP GET for exemple (it happends!) on www.google.com, another IP adress is used in destination (not ANY IP adresse that the DNS resolvers get for www.google.com). So a random web server receive my GET with a host: www.google.com in the HTTP header. Of course the website appear if it doesn't use virtual hosting, or send my a 4xx error. I cannot blame it.

 

I've seen for exemple an HTTP request on www.ac-versailles.com sent to the IP used for google.com. The result : I typed http://www.ac-versailles.com in the URL bar of my borwser and google appear. I tried to disconnect and reconnect the PPPoE session trhoug the webadmin with no success.But, when I reboot the router, the website work again (the good one appear) and some minutes (seconds ?) later another IP adresses are swapped. 

 

Could you tell me where is the option to disable the randomized DNAT, please ? (Joke :smileysad: ) )

 

What's wrong with my hardware, set-up ? It drives me mad !

Are you facing the same problem when you are connected directly to the modem ?

If the computer connected directly to the modem is working fine then, you can try updating the firmware of your router...

Click this link to download the firmware.

I can confirme that a direct connection to the modem works fine. No more scrambled destination.

 

Thanks for the link about the firmware, I saw that there is a more recent one in English language. I'll try it.

A direct connection works fine. The latest firmware update doesn't fix the problem.

 

The router  is useless in this state !

Re: WRT320N randomises destination IP adress !

I don't think I've modified a lot of option from the first one.

 

I've no DHCP configured, all my PC are static

DNS are configured on each PC with Google DNS and doesn't use DNS Masq (DNS forward) of the Router.

Wifi is enabled with WPA2 PSK
