RAM needed for DHCP + router?

Your biggest consumers would be FBSD itself and the routing tables. I *think* 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 likely will. Too many unknowns, like; is this ipv4 only or 6 and 4 routes? Tweaked/minimal kernel, etc.

Subject: RAM needed for DHCP + router?
I'm looking to build a NAT / DHCP box for a lab network for my company. My
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
not much else. I expect the amount of traffic (throughput) to be very
small, but the address space involved is quite large, at least by my
standards. It seems to me that this will require potentially large amounts
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,
depending on how much memory it looks like I'll need. I may also install
webmin for the benefit of my computer-literate-but-not-unix-savvy
