Which "both" sides are you talking about? It's unclear from your question
how the first (non-Squid) BSD machine comes into the picture at all. If
you're using it as a router with gated or a firewall host or something like
that, then it's an issue of using the routing or packet redirection features
of whatever software you're using on it.

If they can't do it, you may be able to use the NAT features of ipnat, which
is part of the IP filters package, but I'm not sure how ipnat would interact
with other software you might be running.

The basic rule is that to do transparent proxying, you need to intercept
at a point "between" the query sources (web browsers) and the Internet.
Usually that's the router for that ethernet segment, an Ethernet switch, or
a firewall. How depends on what you're using.

Hope this helps get you started in where to look.
