We are designing a new setup with a PIX515 firewall and failover. One Internal interface with the application servers on; several external interfaces to separate customer networks, connected via fibre or a router connection.
Due to the failover setup, we need to put in a hub or switch between each customers WAN connection and their interface to the PIX. That means we need to purchase 3 hubs, one for each customer. To provide reasonable service, we should make those manageable hubs.
The alternative is to put in a good switch and split it up into 3 vlans. This would be adminstraticely easier all round. Previously I've shyed away from this as I consider the VLANs and Cisco Switch to be a point of lower security, which could be easily (in comparison to the PIX Firewall) be compromised. But I'd like a second opinion.
I would like some feedback from others on what their thoughts are...VLANs or separate hubs?
Thanks.....Mark Simmonds.
