Multiple site to site VPN
Hello this is my network setup 3 diffrent locations all have 5505 ASA device.
Main office is in norway and all the branch offices needs to be connected to the main office in norway but not to each other.
Currently the main office is connected to the other branch office in a remote location in norway.
What do i need to consider when im going to connect the Norway office with the Shanghai office?
Fixed ip is in place and im able to connect to the shanghai asa device from norway.
Thanks so much.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
No problems - your set up is quite straight forward - if you were to put in a site to site from branch office to branch office them add the following command
same-security-traffic permit intra-interface
but in a simple hub and spoke architecture like you have you dint need that command
other that that you are good to go :)

Where did it all go wrong :-)
I'm not sure what or if there exists export laws between those two countries, but I know the US says nothing above 40-bit encryption is allowed (at least last I heard, not sure if they upped it or not). But since you're connecting sites between different countries, although it is easily technically possible, depending upon the encryption used, it may be illegal.
Maybe PeteLong knows better than me, but its something I'd be looking into anyway especially since one site sounds like its in China (unless its a different shanghai than I'm thinking).
