I *thin= k* full internet routing tables are still less than 512MB, (google to check= ), so unless you have more routes than that - 512MB may work, 1GB most like= ly will. Too many unknowns, like; is this ipv4 only or 6 and 4 routes?

Hello list, I'm looking to build a NAT / DHCP box for a lab network for my company. My= =20 question is, how do I estimate the amount of RAM the machine will need? This box will be running isc-dhcpd, doing NAT either via natd or pf, and=20 not much else. I expect the amount of traffic (throughput) to be very=20 small, but the address space involved is quite large, at least by my=20 standards. It seems to me that this will require potentially large amounts= =20 of memory for routing tables, etc., but not much disk. I'll be installing the latest -RELEASE; 32-bit if I can, 64-bit if I must,= =20 depending on how much memory it looks like I'll need. I may also install=20 webmin for the benefit of my computer-literate-but-not-unix-savvy=20 coworkers. Thanks! --=20 Chris Hill chris@monochrome.org ** [ Busy Expunging ] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
