[Cerowrt-devel] 3.10.32-4 issues

Hi All,

I just upgraded to 3.10.32-4 and locally all looks quite well. Both my macbook and my nexus 4 get stable connections to cerowrt over the 5GHz radio (HT40+ channel 44 country code: DE), also the machine on se00 gets a decent address. That is all machines get decent IP4 addresses, only cerowrt gets a working ipv6 address.
	Unfortunatelly the only machine that can reach the internet is the cerowrt itself, none of the connected machines can reach the internet (they can reach each other just fine)
	Here is a bit information from the linux host on se00:

Absolute path to 'ifconfig' is '/sbin/ifconfig', so running it may require superuser privileges (eg. root).

To me this looks reasonable and I am unsure why the machine does not reach the internet. Interestingly on the first login to cerowrt routing seemed to have worked, but once I applied the set of changes I typically apply to customize cerowrt for my home network routing somehow went bust.

I just noticed that the lan and guest zones were empty, so I ant an reassigned them, but still the connected computers can not reach the internet. If there is anything I can do to debug this, please let me know, otherwise I will ref lash the router back to 3.10.28-16 tomorrow…

Best Regards
