I have a remote LAN which locates inside another company. I would like to set up so that the headquarter LAN can access resources of that remote LAN. The remote LAN does not have any public IP address but it can go thru the other company's network to go to the Internet.
Does site-to-site ipsec work in this case ? Or any other solution can help the main LAN to access to remote LAN ?
Thanks,
DT
