Hi,
Well I finally figured it out. On my ISP's wifi modem/router, there is a setting called 'DHCP Binding'. This can be used to make sure that a certain MAC always gets the same IP address assigned through DHCP. (essentially creating a DHCP scope of 1 single IP and 1 single MAC). When I enable this for a bridged host, reaching the default gateway becomes impossible. I verified the MAC both in the VM settings as in the guest os, and made sure that they match the 'DHCP Binding' settings on the modem/router. As soon as I remove the entry from the modem/router and restart the guest, networking resumes as expected. I had this setting enabled for the 'old' VM's, but not for the newly created ones; which explains the difference in behavior. Now what I dont understand is why such a setting should/does break bridged to wifi networking - especially when at the same time NAT does work as expected with that setting enabled. - Maarten.
