WRP400 nat: disabled => can't reach WAN

[kokoko3k3]

Hi, as stated here:

This router support bridge mode, but i'm unable to configure it.

There's no such option in the web configuration page, but the manual says that disabling nat activates automatic routing mode.

Unfortunately all i get when i disable nat is to be unable to reach any wan address.

By watching the generated routing table on the wrp400 (when in NO nat mode) i see that 0.0.0.0 is correctly set up to use the external border router, but any incoming packet from the wrp400 lan port isn't routed there.

Also, i don't get any dhcp from the external router, this means the wrp400 is blocking it.

Please, explain me how to set up a bridge mode between wan and lan ports, thanks.

In my experience the WRP400 doesn't support bridge mode. You must use a SPA2102 or a SRP520 router/bridge.
