I'm going to be hosting several (probably around 20 to 30) terminal servers for remote clients. I'm looking for a recommendation for a Cisco firewall. I'm considering the ASA 5510. Each client will have a unique "real world" IP address that they use to connect. The firewall will have subinterfaces for these connections. On the back side of the firewall, the terminal servers will be using ip address in the private range. I want the clients to use a real-world IP address and the firewall to forward the traffic (after checking it) to the appropriate internal server.
Is it overkill to use the ASA 5510? Does someone have a different recommendation??
Thanks for the help!!
