ICMP redirects are a bad idea from a security perspective, so I'd stay
away from that. Ideally you should disable ICMP redirects on your
machines because it would let somebody on your LAN do all kinds of
nasty stuff with re-routing traffic.
I question your statement about requiring static routes on 100 client
machines, unless I'm missing something. You should be able to put in
static routes on m0n0wall pointing to that VPN gateway for the VPN
