Cheers for the info John! I'll have a good look.

I've also been looking at the SonicWALL website, and albeit more expensive than an ordinary router, I still think these devices are priced reasonably.

I believe the best choice would be either the SonicWALL TZ 150 Wireless or the SonicWALL TZ 170 Wireless. (European pages with detailed spec PDF's here (150) and here (170)

Which one would be the best choice for what I want to use it for? Remember, I would normally never need any more VPN connections than three. (usually only one, possibly two)

What is the difference between those two? I see the 150 only supports site-to-site VPN tunnels (which is what I need I think), and optionally also Global VPN account licences (what is this?).

The 170 wireless seems to support both? There is also talk about 10 node support (2), 25 node (10) and unlimited node support of the 170. I don't see this in the 150's spec sheet. What exactly is this, and do I need it?

I also see both these routers have anti-virus, andti-spyware and intrusion prevention features built-in. Very cool! Of those first two, I never knew this was possible in hardware. Is this reliable? (anti-vir and anti-spyware I mean) Does this mean I do no need to install an anti-virus package on the pc's anymore??

Any other important differences between those routers?

As always, a big thanks for any info you guys can provide!
