Read again Corona688's post#5 and post#7.
You do seem to be hell bent on spending good money on this when the best solution is to get hold of a piece of junk somebody has thrown out and put a second NIC in it. It will give you a choice of almost any Linux version to run on it and a choice of any decent open source firewall (eg, IPcop). You can quickly get to the situation where nobody can as much as sneeze on your LAN or WAN without you knowing about it. You can also police the whole thing and allow/disallow anything you want.

srtconfig
SRTCONFIG(1) BSD General Commands Manual SRTCONFIG(1)
NAME
srtconfig -- configure srt interfaces
SYNOPSIS
srtconfig srtX
srtconfig srtX N
srtconfig srtX del N
srtconfig srtX add srcaddr mask dstif dstaddr
srtconfig srtX set N srcaddr mask dstif dstaddr
DESCRIPTION
srtconfig configures, or queries the configuration of, srt(4) interfaces. An srt(4) interface parcels packets out to other interfaces based
on their source addresses (the normal routing mechanisms handle routing decisions based on destination addresses). An interface may have any
number of routing choices; they are examined in order until one matching the packet is found. The packet is sent to the corresponding inter-
face. (Any interface, even another srt interface, may be specified; if the configurations collaborate to cause a packet to loop forever, the
system will lock up or crash.)
When run with only one argument, srtconfig prints the settings for the specified interface.
When run with two arguments, srtconfig prints the settings for the routing choice whose number is given as the second argument.
The form with 'del' deletes a routing choice, identified by its number. Other choices with higher numbers, if any, will be renumbered
accordingly.
The 'add' form adds a choice; the other arguments describe it, and are documented below. The new choice is added at the end of the list.
The 'set' form replaces an existing choice, given its number. The other arguments describe the new choice which is to replace whatever cur-
rently exists at the given number N.
A choice is described by four pieces of information: a source address and mask, which are used to determine which choice an outgoing packet
uses, a destination interface, and a destination address for the new interface. The source address and mask are specified like any Internet
addresses (for convenience, the mask may instead be specified as a '/' followed by a small integer, CIDR-style; note that in this case the
mask must still be a separate argument; it cannot be appended to the end of the source address argument).
Each srt interface also has ordinary source and destination addresses which are set with ifconfig(8) like any other interface; these should
not be confused with any of the above.
