No manual DNS setting in PPPoE mode.

[GoogleCodeExporter]

In WAN >> Internet 
Access Connection Type set to PPPoE and Fixed IP(IPCP) set to No
PPPoE working fine, but only with DNS servers automatically assigned by ISP, 
and no way to use any other (like google open dns).

Q1: Is it possible to add manual dns assigment in future firmware version?

Q2: How to mannualy assign custom DNS servers for PPPoE WAN connection via SSH?

Go to LAN >> General Setup
And on the right side you will see
Force DNS manual setting
Check the box to enable and enter your own DNS-Servers

I have the same problem with WAN in DHCP mode. Manually forcing DNS servers 
doesn't work.

I am trying to configure the router to use the OpenDNS servers. But even when I 
enter the IPs in LAN > Generel Setup > Force DNS manual setting, the clients 
are still not using the OpenDNS Servers, which can be tested by visiting the 
OpenDNS welcome page (http://www.opendns.com/welcome/).

Before testing I cleared and flushed all possible IP caches in the OS, browser 
etc.

Any help would be highly appreciated.

Btw: When I google OpenWRT and OpenDNS there comes up a lot of "workarounding" 
and stuff, so there really might be an issue here, but I'm not an expert.

Similar problem in PPPoE mode with firmware 1.5.2

DNS servers set to OpenDNS (208.67.222.222 etc.)under Force DNS manual Setting 
on LAN page. All works fine for a while then DNS lookups no longer go to 
OpenDNS but to ISP servers (even though DNS server IP addresses passed to PCs 
correctly).

It appears as if DNS requests are being rerouted to the ISP servers.

Setting back to using ISP servers by unticking the Force DNS Manual Check box 
and then re-inserting manual settings and starting again restores normal 
operation!

Is possible to set DNS manually with telnet?

I tried, but no luck.
