[Shorewall-devel] multi isp and failover

[Natanael C. <nat...@gm...>]

Hi,

I am looking for a failover solution that would work toghether with
shorewall multi isp setup http://www.shorewall.net/MultiISP.html

I'm thinking of writing a daemon (in C?) that pings upstream default
gateway (or configurable host) and when isp goes up/down, it executes
scripts to add/remove the routes to ISP.

Does anyone have such a solution already?
What would be needed to integrate this with shorewall?
so far it looks like I would need to refresh shorewall on up/down
events, which is awfully slow. those routers does not run perl.
(shorewall-lua rewrite anyone?)

other ideas?
