I have a client who is replacing their DSL with a multi T1 connection and we want to upgrade from the somewhat unreliable linksy/dlink/netgear type router/firewall to something we can depend on. They have about 70 internal users and 25 external users (some OWA and some Terminal Server), but will probably double this in the next 2 years.
They are receiving a dual T1 connection with a few VOIP phone lines. The telco vendor is providing a Cisco 2600 series router, but we do not have access to the configuration, basically they are providing us with 5 static public IPs off of the 2600 and it is up to use to bring it into out network.
I want to take the Public IPs from the telco and port map them to machines on the local network including Exchange, http, https, ftp, sftp, RDP, and a few others.
From what I understand I don't really need a router, but I do need a firewall. Will a Cisco PIX 506E of 515E do the job or will I need another 2600 series router? What about the Cisco 801, is this a router/firewall combo that will meet my needs (the price is certainly right)?
Do the PIX firewalls allow what I guess would be NAT (not really routing right?) from the outside public IPs through the firewall to the inside private IPs?
Is the Cisco SmartNet warranty service worth the expense?
