Gene, I do use the firewall in my ISP supplied router, but I don't know how that stacks up against DDWRT. I do have a flashable router in the cupboard, so I might just give it a try.</div>

I would add that the best place for the firewall is in your router, by <br>
reflashing it with dd-wrt. In 2 decades of running it that way here, no <br>
one has come thru it to gain nefarious access has managed to do so. By <br>
putting your switch on the local side of your router, you have the run <br>
of your local network, with no firewalls to have to putz with but <br>
dd-wrt's sharp teeth are keeping the black hats out. Not to mention it <br>
has no TLA back doors.<br>
<br>
