yes, the e1000e NIC is serving the NATed Windows client.
The setup was outlined here:

I didn't do anything(tm). This report sounds like the same issue:
http://ehc.ac/p/e1000/bugs/378/
Oliver Wagner wrote the problem started to appear
after updating from kernel 3.5 to 3.8.0.35 (new frag size code).
I just noticed now he wrote he has two identical boxes:
---------------------------------------------------
- Box with symptoms: Router/Firewall, packet forwarding
between different VLANs on eth0 and eth1
- Box without symptoms: Fileserver, eth0/eth1 bonded
(VLANs used, but no forwarding)
---------------------------------------------------
So it looks like it's related to forwarding somehow,
I've made the same experience IIRC.
Cheers,
Thomas
