TCP over loopback works fine. TCP to LAN hosts works fine. UDP and
ICMP to any hosts works fine. Inbound TCP from anywhere works fine.
It's only routed (non-LAN) outbound TCP that's the problem -- and only
from the problem host; all my other machines on the same LAN are still
in good shape.
I ran tcpdump on the problem host and saw only SYNs being sent. I ran
tcpdump on the target host and never saw the inbound packets.
There are no iptables rules; it's ACCEPT across the board.
Ordinarily, I'd look for routing problems, but routing would also
affect UDP and ICMP, right?
