I don't know if it's related, but I've had problems with packets to/from a recent -CURRENT box not being able to traverse a pf (running on 6.2-stable) firewall with NAT and state rules. Some of the packets are dropped unless I disable net.inet.tcp.rfc1323 on the system running -CURRENT, enough to cause ssh connections to stall and drop before login. 6.x machines behind the same firewall work just fine. I can provide tcpdump output if someone thinks it will help. Craig
