Search Again: FW: DNS Port(s) From: Simon Forster Date: Sunday, March 5, 2000 Time: 1:57:00 pm > Zone transfers usually happen through TCP port 53.

As someone else was asking about firewalls in today's digest, I'm running IPNR from Sustainable Softworks <http://www.sustworks.com/> using NAT and IP Filtering. For someone with my knowledge of routers (zip), this has been an interesting learning curve. The principles are fairly simple but do take a little while to get to grips with - and then you have to apply your knowledge. i.e. if using IPNR, expect to have to work at it a bit. IPNR sells for $89 and is a software router that you'll need to run on a Mac running Open Transport. I would suggest buying the $109 bundle though which gives you some basic network tools so that you can try to work out why things aren't working as expected. To be effective, the Mac you run IPNR on needs to have two network cards. One is exposed to the internet, the other to your sanitised LAN. So, while the software is relatively inexpensive you do need to purchase another network card (not too bad either) and set up a Mac with IPNR. Your biggest expenditure will be in time. The other way to go is to buy a dedicated router. The favourite here seems to be from Sonic Systems(?). Someone has mentioned this already and gave <http://www.sonicwall.com/products.html> as the URL. My take so far: IPNR is a great tool, allows you to set up a fairly robust firewall and you'll learn shed loads while playing with it. However, it's not a dedicated solution and is unlikely to be as robust as something like Sonic Systems products.
