I recently purchased a Cisco ASA 5505 (Version 7.2(2)) to replace our current Xserve firewall solution. I need some help to configure this thing. I need 2 vlan's, one for outside, one for inside. 188.8.131.52-26 is my ip block and here is the current setup:
Internal ip block is 192.168.150.0/24. The exchange machine is connected to 184.108.40.206 and forwards to 192.168.150.103(externally accessible at mail.domain.com, entourage.domain.com, exchange.domain.com). The internal users go out via 220.127.116.11.
What I need is for users to be able to come in via VPN as well as access OWA from anywhere. Users also need to access http, https, smtp. Currently our vpn solution is to use the xserve to host the vpn connections and logins and would like to use the ASA 5505 to do the same thing (create user accounts for vpn login), if possible. I also see an email proxy setting on this device and was wondering if I could use that to allow users to retrieve email in outlook from the internet? I have tried rpc over http but we have some issues that cannot be fixed right now. Please let me know if more information is needed.
