- A solution for Peer-to-peer NAT and BEHAVE: Jesse Peng provided
the idea. Basically, a P2PNAT target which keeps a hash table to
ensure we don't allocate the same source IP/port to two NAT
connections. This allows us to do hairpin NAT (it probably needs to
set up an expectation to catch these). Also needs to set a flag so
TCP window tracking will allow simultaneous open, and not drop
immediately on RST (the latter can happen if the other end firewalls).
- Nfsim seems to be attracting more of a following in the core
team. Joszef committed window tracking tests! Harald wants netlink
support, and also an actual nfsim release. I applied updates for
2.6.14 (thanks to Max Kellerman), and cleaned up the tests a little.
- More thinking on the use of a hash trie and progress. There are
several benefits for speed and scalability, although the are still

- Possible simplification and scalability improvements on the
expectation code. It's more general than it needs to be at the
