Cisco, Cisco ADSM, ASA 5505

I'm new to cisco products. My company just procure 2 cisco ASA 5505 for site to site VPN between our head office and branch office. I know the subnet mask and ip range for both networks. My problem is how to configure the ASA for site to site connection. Another issue here is that in my head office, there is a sonic firewall that NAT all our traffic across the internet and as it stands i cannot remove it but i have to place my ASA behind the sonicwall. How can i achieve this?

As for the sonicwall you would need to forward ALL VPN Protocols and ports to the ASA inside (your IT will probably say NO when you ask them)
Anyway site to site VPNs are easy to set up see my website here

Thanks Pete. On my ASA i have this error 'You are authorised to access home and monitoring views' so can go to configuration mode.

For the Sonicwall...Please explain how you want me to forward VPN traffic as am told the ASA should be behind the sonicwall.

Please how do i reset my ASA 5505 to factory default

I have used cisco recommended
config factory-default
login on thru still requires a password as against cisco blank username and password.

i have another error 'You are authorised to access only home and monitoring views'

With this i cannot run the wizard for site to site vpn.

Any ideas on the way forward for me.
