I have been trying to setup a 506 to serve as a firewall for a small local church. I have been banging my head against this and finally need to reach out for some assistance. I have read through too many different configurations and tried most of them without success.
Here is what I am trying to achieve in a nutshell.
A 506 connected to a cable provider with a Dynamic DNS service. From this 506 I want to:
1) Protect the internal network
2) Provide access through the PIX to a web/mail server inside the network.
3) allow remote access VPN connections with RADIUS authorization.
I have been able to do the following combinations:
1 and 2 working together without problem. I can access the Net from the inside network without problems and get traffic in to the web server and the mail server.
1 and 3 working together. Protection and access for internal network is working fine with VPN access for remote clients.
What I have not been able to get working is having the VPN working and allowing access to the web/mail server at the same time.
I am certain that I have missed something simple in the configuration, unless this is just not possible.
