I am trying to create a site to site VPN on two ASA 5505's , I have already have three VPN's working so don't feel confident making changes so I'm using the ADSM for ease.
This remote site has an internal address of192.168.6.0 but we have just changed ISP providers and the set up they use has confused me as to which range I use.
The router has an IP address of 10.0.2.27, gateway 10.0.2.25 which then translates to a public IP address of lets say 220.127.116.11.
I have this side packet transferring to my main office ok but from the main office I am unsure how to configure the site to site.
Do I use the inside network address range of 192.168.6.0 ? I cant seem to get the main office site to site working or should I be using the 10.0.2.27 address somewhere?
