Hey there,

I just did another physical-to-VE procedure. Done it before with no problems, but this one gives me a headache.

Some relevant lines:

Now.. maybe I'm not seeing it, but this looks all fine to me. Yet.. no traffic possible, not in, not out. Any hints?

Hello,

Do you have others VEs which are running and with a working networking on your HN ?
Maybe the problem come from the HN ?
Do you have a good /etc/sysctlf.conf ?

Yes, I do have other working VE's on the HN. Also: I vzmigrated the VE to another HN.. same problem. The second HN also has other (properly working) VE's.
