Firewall Speed

Hi everyone Happy new Year to all. I have some questions. I want to use an 486 DX 33 with 32 MB Ram as an Paketfilter Firewall with IPChains on a SuSE 6.3 System in an 100 MBit Lan enviroment to connect 2 Networks. Is the Maschine Speed fast enough to do the Job (Down or Upload with the full 100 MBit/s ) ????? Or shall i use an Pentium ???? For an ISDN Router with IPChains is it fast enough to use the full 64 KBit/s. I use it at home. Does anyone known about an free application Firewall for HTTP, FTP, DNS , ....??? Is the Squid an application Firewall ???? I think not !!!!! MFG Stephan Gerling gerling@kub.de
