i've a situation where the network we're building is very low-traffic, but requires maximum uptime. the budget is for all components to be duplicated to allow for failover. i've figured out various ways to do load-balancing and failover at the router/nat level, and at L2, but have run into a bit of a problem figuring how to use two solaris boxes (firewalls) as gateways for all servers/clients behind them in some kind of HA/failover configuration. i'd like to minimize the client/server side configuration as much as possible (and the environment may include NT, Macs, or other such ilk which will not easily supporting a useful routing protocol), so something like installing gated on all of the boxes, and implementing an ospf environment is an unsavory proposition. i'd like something like HSRP, but for solaris/unix, and preferably free. i'm aware of several vendor HA solutions, but they are mostly overkill for our application. i've looked into IRDP (rfc1256), but i cant find any information about vendor support. any pointers to relevant info would be appreciated, including any general resources for HA/network redundancy/failover stuff (preferably non-commercial). -foo
