[ale] Can't ping localhost

[DJ-Pfulio]

Nope.  I dumped all the FW rules and grep'd for '127.0' - nothing.
Also, nothing in any system logs, FW logs or dmesg.

I do see lots of multi-cast broadcasts being blocked - 224.0.0.1.

SMTP is listening on port 25/tcp.
$ netstat -an | grep 127.0.0.1
tcp        0      0 127.0.0.1:25      0.0.0.0:*               LISTEN
udp        0      0 127.0.0.1:123     0.0.0.0:*

This is expected.


More ideas?
