[Shorewall-users] Proxy ARP with Failover Doc

I wrote a brief document outlining a Shorewall implementation consisting 
of two firewall servers running in a fail over configuration using the 
heartbeat program.  It may be found at:


There is nothing groundbreaking here, but it does address a way to have 
Shorewall actively running on multiple servers while not causing any 
conflicts with proxy ARP configurations.  This document may be of use to 
those who use proxy ARP, want redundant firewall servers, and need an 
active firewall running on each of the firewall nodes, (e.g. you need 
network connectivity but do not want an open interface like the 
routestopped directive would do).
