Good morning guys and gals,

We have a 48Si that we would like to setup in a hosting environment. Essentially we have a class C of external IP addresses, and we want to link external IPs to internal devices. We would like the internal devices to see the gateway (so the firewall permits traffic) but in case a hosted device gets compromised, we don't wnat that machine to browse the other vlans.

Essentially we would have a gateway of 192.168.70.1 (default route) in the switch. We would then have VLANs Host1 (172.16.4.1/29) then Host2 (172.16.4.9/29) then Host3 (172.16.17/29) and so on. We would like each Hostn VLAN to see the internet gateway (via ipforwarding) and vice-versa, but not see each other.

Would you anyone have any suggestions for how to go about this?

Thanks in advance as always!
