Can you provide:
- routing table from fw (also -t nat)
- routing table from new netvm
- firewall from fw
- /etc/resolv.conf from fw

Found that it is caused by DNAT rules in PR-QBS chain, looks like bug in kernel (iptables).
Next step: check if it is fixed in 3.2.x (on my system it works on 3.2.5).

This seems to be a problem with my USB driver. The netvm switching does work when I have a different NICs assigned in the netvms. So, seems Qubes-irrelevant. Will try some newer VM kernel, which should solve it.

After all, it turned out to be a problem with Xen net backend -- it was just that the usb modem I was using was apparently triggering this bug:

Here is essential patch:

But also fixed problems mentioned in #465, making easier use it in qubes-manager (setter in netvm property)
