Site-to-Site VPN with Cisco 891F routers

Hi all

I'm new to Cisco world and just finishing CCNA with little experience in Cisco devices so any advice would mean the world to me.

I was given a task to create Site-to-site VPN with two Cisco 891F routers. The problem is that one site has a static IP address while the other has a dynamic one. 

Also the setup has to deliver a remote access to VPN using Cisco VPN Client or AnyConnect software.

My question is: Is this kind of connection even possible with these routers and if not, what kind of additional equipment do I need?

                         Can I configure the router that is installed on the site with dynamic IP to work with the free DNS services like no-ip?

                         Can this kind of setup (if it's even possible) accept adding a third router with static IP in the future?

With best regards

Hi

Hi

this is how you build a lan to lan IPsec tunnel between 2 800 series and yes they support it with a security license , you really should have static both ends ,I have not done it before without static so I cant over advice on that end of things but I I provided a doc on it , 1700 setup is same as 800 setup in ios , by the way this will half the throughput of your link when IPsec is enabled due to overhead
