PaulI'd agree with your choice there. If you want more than one PC connected to the Internet then a router is the only way to go. I use a Cisco 1603 here with an ISDN connection and Cisco's firewall software.
You'll definately want to take a look at what security you have. Network Address Translation (NAT) will provide some protection from people attempting to make connections into your network, but if you can do packet filtering then I'd recommend some anti-spoofing measures (basically block any packets on the ADSL interface which purport to come from or are addressed to your local IP addresses).
Also, a biggie, turn off any remote management that the router has, or severely restrict who can access it.
ADSL is not going to happen here for years (and that's an optimistic estimate). Satellite will be problematic because there are some high trees that I don't own interfering with my line of sight to where the satellites are. Cable - never. Looks like it's Frame Relay or Leased Line. Where's that checkbook
Wish me luck. Cisco CCNA exam on Friday.
