Hello Dexuan,



It seems, it is not completely correct, although the effect is as if it is =
not working.

Systat -ifstat 1 shows this:

[cid:image001.png@01D158E2.E7296D00]



So something is happening. But I can not reach anything. And the server can=
 not be reached from the lan (hn0) or internet (hn1 and hn2).



I get a firewall message in /var/log/messages (first message from 11:18:55)=
:

[cid:image002.png@01D158E2.E7296D00]

But this is just caused by the problem?



If I can help with further information, please let me know.



Regarding Bug 187006, all interfaces have fixed addresses.



With kind regards,



Jac
