Hello, I'm going to be setting up a site to site VPN using our Cisco ASA 5505. The two sites are laid out like this: Site1 has an a Domain Controller running SBS 03 and is setup as a DNS, DHCP and Exchange server which is behind a Cisco ASA 5505. Site2 has a Domain controller running W2k and is setup as a DNS, DHCP server which is also behind a Cisco ASA 5505. Internal addresses for both sites are the same 192.168.1.1-.254. I'm really looking for thoughts on what would be the most logical way to set the VPN up because I'm not sure if: 1. if you have to change one of the sites internal IP subnetmask. 2. if you'll have to change the Cisco ASA 5505 internal address on one of the sites. 3. If you have to turn DNS and DHCP off on one of the servers. 4. If using the VPN wizard on the Cisco ASA will take care of all my listed problems. 5. Should I create zones with the servers to make this whole thing easier.
I really don't want to use the W2k server on Site2, I am actually thinking about taking it out of the picture and later upgrading it to SBS 03, so what I was thinking of doing was just taking that server out, change the internal ip of the site2 Cisco asa and then joining the sites via the VPN wizard. Does that sound like it would work or does anyone see any problems with that? Thanks for any input.
