[SFS] [lug] networking question

[David L. Willson]

TY for all the responses. I can't try anything until at least Tuesday, but if all goes well, I'll try carving off the subnet on Weds or Thurs. If it works, I'll let you know, and I'll ask my ISP if I can move to a bigger subnet (/27), so OpenStack gets a /28.

For those that offered actual on-the-phone help. TY and I'll follow-up on Thursday if my experiment goes hard, which seems likely.

For those that suggested NAT, it's a great idea, but I don't think it meets the need for OpenStack.

For those that asked why I'm trying to do:

> What's the goal here?

I want to give my friends a whole OpenStack to play with. An OpenStack wants a routed public (at least public-seeming) network inside, among the many other demands it makes. I've done it with RFC-1918 networks, and it worked internally, but I really want it to work externally, someday, too. So, I asked my ISP if I can rent another subnet and put it behind a router of my own, and they said, "Nah, you can't." So, I looked at renting a subnet and a physical machine from logicweb, which would be similar to what I did at Delimiter until they became so horrible that I couldn't even with those guys anymore. But, the logicweb solution would be nearly $500/month between the subnet and machine, so that's also a "Nah, I can't." So, in desperation, I thought, "Maybe I can split my measly 16 addresses into two subnets." It wouldn't really work, though, now that I think about it, because OpenStack consumes addresses at about triple the rate I'd naively assume (i.e. nothing like 1 EIP to 1 IP, more like 1 EIP to 3 IPs). Short story very long and convoluted, I'm trying to do OpenStack for my learners and do it on the cheap.
