They were all origional Apple products. 7200, 6500 (which has no built in
ethernet), and beige g3 (oldworld).

What's your best uptime for the g3? I have one setup as a ipsec
gateway/firewall, and it didn't last over 28 days. Add a tulip card (it
already had one for firewall, now has two...) and I now have 70 days uptime.
Also note: Mace has only worked over two days for me in about 20% of my
7200s (I have about 15) and in the case where it was able to reach 14 days
uptime, I was seeing kernel memory corruption, but no oops or crashes, just
owkward behavior. Same solution, add another ethernet (this one has
eepro100, and tulip) and it now has 90 days uptime.
If anyone wants to try to fix the mace driver, I'd be happy to test any
