Thanks Alexandre,
I must have changed something wrong in the log.
It's OK in the /etc/xen/fw.cfg:
vif = ['bridge=breth,ip=7.5.7.202, mac=00:16:3e:07:d2:01 [...]

Excuse me for misunderstanding
Anyway, I assume it does not working still.
Is "00:16:3e:07:d2:01" the MAC your ISP knows and trusts?

Install tcpdump on your Dom0 and sniff the traffic on breth and eth0. Make sure the outgoing traffic (A) is there, (b) has correct IP and MAC information. As you mentioned that you have changed nothing, then it's probably your ISP's fault. The tcpdump log would work as "troubleshooting evidence" with them.

tcpdump -e -i breth
tcpdump -e -i eth0
Then ping some IP from your DomU. Start with your default uplink gateway.

Take in account, that a paranoid ISP configuration may react to a MAC change or if it see more than one MAC on the port, which is your case: they can "see" on layer2 level your Dom0's MAC and your DomU's MAC, and think you are doing something weired.
