Transparent Redirect From Router

I'm trying to setup my router and squid box so the move will be transparent
to my users. I have tried several setups and I THINK the problem lies with
the route-map on the router but I can't be sure. If you have a setup I can
copy that would be great, otherwise here's what I have on the router:

 <<router.txt>>
The redirect on the squid box to send traffic from port 3128 to 80 is:

# IPCHAINS rules to allow transparent proxy with squid
#
# Accept all on loopback
/sbin/ipchains -A input -j ACCEPT -i lo
/sbin/ipchains -A input -j ACCEPT -p tcp -d 10.10.88.2 80
/sbin/ipchains -A input -p tcp -d 0/0 80 -j REDIRECT 3128
/sbin/ipchains -A input -p tcp -d 0/0 81 -j REDIRECT 3128
