I would like to know if a Cisco 506E can do all of the following simultaneously (I have 4 useable public/global IP addresses to work with):
1. site-to-site VPN
2. client-to-site VPN using Cisco client
3. use one IP for a mail server that is running Exchange and OWA, i.e. static NAT allowing incoming 25 & 80 and insure that outgoing mail will use the same public IP as is the incoming (for Reverse DNS lookup issues).
4. use another, via NAT I assume, available public IP for Internet browsing by multiple users on the private side.
I currently have the site-to-site up and running, and have another PIX that is doing the NAT for mail and outgoing Internet Access, but would like to consolidate into just 1 box rather than two.
thanks in advance,
