SubjectPROBLEM: netfilter + 2.4.0-test10 causes connect:invalid argument
1. running 2.4.0-test10 with netfilter/iptables 1.1.2 ping/telnet gives
you invalid argument when connecting to ports on local interfaces.

2. when connecting to local interfaces (and/or local aliased
interfaces) from the local machine, ping/telnet (to any port) gives you a
connect: invalid argument. the connection works fine from remote systems
(eg. telnet remote 80 works, but telnet localhost 80 gives
connect: invalid). noticed same problem on a box in 2.4.0-test4.

3. networking

4. Linux version 2.4.0-test11 (root@amdbox.opaquenetworks.net) (gcc
version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #3 Sat Dec 2
