It should also be noted that VPN requires significantly needs more CPU power than ordinary routing. • Memory The amount of memory determines the number of concurrent connections the firewall can handle. Memory size also has an impact on performance. A firewall with one or several VPN connections will require more memory. • Disk space The log functionality can generate large files. Make sure enough hard disk space is provided to serve the organization’s network logging policy. A SCSI disk is preferred if you have demanding logging requirements. • Network devices ISA cards are not supported by the Trustix Firewall server. 32 | TRUSTIX™ ENTERPRISE FIREWALL 4.6 USER GUIDE
