But the post you are referring to, are about dynamic interface/bridge, not about authentication issues, like stated in posts 114, 97 and 95.See post 117 and 121 above.
It will be fixed in a later version.
I receive my wan ip by dhcp (my isp is Orange France), of course a release/renew of the dhcp client do not help.How do you receive WAN IP by PPPoE or IPoE(DHCP)?
