Re: Firewall Speed
I have a Pentium III 600Mhz 720MB Ram running FreeBSD 4.10 with IPFW+Nat+Squid+Qmail with Clamav+dnscache, routing 4 internal networks (around 500 users), 3x 2Mbit/s links and a 1Mb internet link. Everything works perfect !! I will change the machine by the same problem that Josh said.

CPU usage was usually around 1% and load averages .03 or so. Latency and throughput were both acceptable. The only reason I replaced the box was it was a single point of failure and the hardware was old enough that I was afraid there would be some sort of show stopper breakdown. -- Thanks, Josh Paetzel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to " [EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Firewall Speed
I want to run 6.1_RELEASE with Packet Filter(PF) configured as a gateway using 2 identical 10/100 nics, on an old 450mhz pentium with 256 meg ram and an 8 gig HD. In general, should I expect any speed performance issues with internet access base on the processor, ram and bus speeds of the MB? Would the PF config cause any speed performance deficiencies? I had same setup as above but with IPF firewall and received complaints about surfing speed so I put them back on a Linksys router firewall. bc ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
