I have one remote location with Aztech ADSL modem having dynamic IP. We have a non configured Cisco 1841 router at remote site. At main site we have leased line with static public IP having Cisco 1721 router with juniper firewall. How we can make a SITE to SITE VPN over Internet from main site to remote site that remote site alreadt have AZTECH ADSL Router & non configured Cisco 1841 router. Is it necessary that remote site should have leased line with static public IP or we can use AZTECH ADSL rohter’s IP.
