24.3. Network security

If you are linking you LAN to the Internet using PPP - or even just to a "foreign" LAN, you need to think about security issues. I strongly urge you to think about setting up a firewall!

You should also speak to the LAN administrator at your site BEFORE you start linking to foreign LANs or the Internet this way. Failure to do so could earn you anything from no reaction to really serious trouble!
