Re: RV340 Error messages

Hello @gjr ,

the first one is not a true issue 127.0.0.1 cannot be used as a DNS server as it is the local loopback in TCP/IP stack.

 

The second one looks like more serious:

>> kernel: [ 1845.205993] ICMPv6: RA: ndisc_router_discovery failed to add default route

If you are using IPv6 and IPv6 routing this can have an impact as it tells that the neighbor discovery process of ICMPv6 was not able to add a default route that likely is present in a received router advertisement RA likely from provider router.

 

If you are not using IPv6 you can ignore the second message too.

 

Hope to help

Giuseppe

Re: RV340 Error messages

Hi, Thanks for that. I'll ignor the first one for now.

 

Can you give me any pointers re the second? I am using IPv6 and have only just got it working on the RV340 by turning on 'Router advertisement' which was off by default. I have to sat I'm a bit out of my depth with IPv6 and its implications especially with BT's implementation of it!
