ping works not on all sites

["Timo \"Blazko\" Boewing" <blazko@online.de>]

Hello everyone,

I have a strange problem: I am using german DSL (T-DSL) and can reach
almost all sites. However, some sites cannot really be contacted from my
station. DNS resolve works, cos I get the IP from that site when pinging
as well as the real hostname of a destination machine.

I know from collegues that they can contact those sites using the same
provider and DSL. Only the same sites do not work since I have DSL. It
is not a temporary problem.

I am using unstable/sid with pppoe userspace from roaring penguin.

Thanks for any help,

Timo
