One problem remains:

The problem here is that sks hash queries don't behave well.
The server sends a simple "POST /pks/hashquery" without "HTTP/x.x".

Your HTTP proxy immediately responds with "502 Proxy Error" and drops
the connection. I don't even know if a proxy could be convinced to pass
on these requests.

The issue appears to be old and several servers already applied patches.
I just modified mine and posted the patch here:
http://code.google.com/p/sks-keyserver/issues/detail?id=5

So your key server can receive missing keys from all its IPv4 peers, but
it can't distribute new keys to unpatched servers.
