Is that a _real_ issue to worry about, Hans? If a customer is IPv4-only, and his provider decides to offer IPv6 too without telling the customer, I don't see that changing anything for the customer. [snip] I think so. Systems can have their dhcp-set-up in different ways: IPV4-ONLY, IPV6-ONLY and both IPv4 AND IPv6. As long as your provider only hands out v4 addresses, all works well, and the client just keeps on polling for ever. But as soon as your ISP "sees the light" and gives you both an v4 AND and v6 address, and your v6 rule-set is "accept anyone from anywhere" you might (!) end up in shit-creek. <<<<<< find your system compromised. Unless you have your ip6tables rule set changed to default drop-anything, which implies that one has started to think/do something with IPv6, which was the main issue i made.
I was considering that most consumer/commodity ADSL boxes do not yet support IPV6, so the provider can advertise IPV6 as much as he wants, it won't cause a problem. That was what happened on my system. Anyway, what are the default SuSEfirewall settings for IPv6? /Per -- Per Jessen, Zürich (12.2°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
