Has anybody else encountered this? Also, if it's already been fixed somewhere, I'd love to know. Any Netfilter debugging tips would also be appreciated.
Turn off tx checksum offload in your domU's using ethtool. We had fixed some forms of NAT with our checksum offload, but maybe not for your type of setup.

That fixed it.  Thanks!

It would be interesting to know more about your configuration, and also what Xen version you were using. Changeset 9579 fixed some bugs, so if your repository is older than that then you might well see problems.
