Most of what I read talks about NAT or Juniper SRX machines. But, what if I have 100 customers each wanting public SSH access, how does that then work? Surely then NAT will not cut it. 2) Also, on a practical note, how would this be physicall connected e.g. setup:- 1x switch 1x linux firewall 1x management server 1x nfs server 2x hosts Would I trunk a public network to the uplinks on my switch, then add the public VLAN to the ports the hosts are on. The firewall can do NAT and port forwarding for the management LAN. Does that sound right? Many thanks, Jon Need Enterprise Grade Support for Apache CloudStack?
