I believe this message indicates that a "-O" rule or policy is denying
transit. Check your default policies.

Is this properly constructed? I don't think that you need to use
'accept' with masquerading rules.

I don't believe you need this masquerading rule. I'm using ipchains now;
I use the diald ip-up and ip-down options
to specify a scripts that bring the firewall up or down when the link to
the ISP comes up or down. When the link is
down, I permit all forwarding.

You might want to try:
ipfwadm -F -a accept -W $DIALD_INT -S $PRIVATE_NET
