Hi there,

I've been using the multi-isp functions in shorewall for years, and
recently updated my version of shorewall and the failover scripts I've been
using have stopped working (swping).  I've also tried to make FOOLSM work
without any success.   I've modified my old version of swping to use the
firewall disable/enable methods vs. updating the status files. It's
attached.  But neither my hacked version of swping or FOOLSM seem to work.

Here seems to be my problem:  Either can correctly detect a down internet
connection, but once it calls ${VARDIR}/firewall disable ${DEVICE} then no
more packets can be sent out via that internet connection so the script
can't successfully determine when the link is back.

It is possible this is because one of the links is an usb wifi dongle, and
that's breaking something. Its also possible something else in my configs
is breaking something?

I don't see any blocked messages in my logs.

Internet connections: wlan0 & eth3.  I've attached shorewall dump and the
swping config I'm using.

Any ideas?

Thanks in advance,
