Need help with Cisco ASA5505 setup (upgrading Linksys RV042 to Cisco ASA5505 50-user)
Posted on 2008-10-17
I should replace Linksys RV042 router with Cisco ASA5505 (50-user license). The office where RV042 is right now is about 30 miles away, Cisco ASA is on my desk at home, I do have an remote desktop to the server and RV042 and I should do the exchange on Monday so I have 2 days to do the setup.
Right now the network in the office where new ASA should go consists of Siemens T1 router, RV042 is hooked up to Siemens and to 48-port switch, 3 Windows 2000 servers (domain controller + 2 applications/database) and about 40 Windows PCs, and two remote users connected via VPN.
This is my first Cisco device so I do not have any experience with CLI. Initially I've tried to use ASDM to configure it but stacked on first step: device IP address which should be 192.168.0.1.Once I hit "Apply" the connection to device is lost and nothing changes. So I learned how to use CLI at least to reset the device to factory settings :-).
I also tried to obtain some guidance from Cisco Web site but it looks like it is oriented to experienced users and there is no guides for entry-level users that just stepped up in this technology.
Below are some details about existing config I should have on the end on ASA:
DHCP server is running on RV042 router, IP range 192.168.0.10~199
Router IP: 192.168.0.1
AD server IP: 192.168.0.5
WAN IP: 63.xxx.xxx.3
WAN GW: 63.xxx.xxx.1
Port 3001 TCP/UDP forwarded to 192.168.0.202.
There are probably some routes applied on Windows Server directly using command line which I may need to add on ASA as well.
ASA should be programmed and prepared so once I am in the office on Monday morning all I will have to do is to swap devices so the downtime is expected to be less than 5-10 minutes. It is production environment with users using database, shared folders and Internet to connect to hosted Exchange server via RPC.
I will need your help setting up this ASA using settings above. Lets start firs with device IP address change. If we will use CLI, please provide necessary commands I have to type. If you need any information about current config, let me know how I can list it on the screen.
ADSM version: 5.293)
ASA version: 7.2(3)
Thank you in advise.
P.S. Is it any way how I can test and verify the result without being in the office where it will reside?
