HI , I have ASA 5510 connected to Speedtouch ADSL router modem ,There is no static public addres the only public address is the dynamic address associated by the ISP to the Sppeedtouch ADSL modem,Is it possible to configure ASA to accept VPN to my local network?
In a previous lesson, I explained how to configure a site-to-site IPsec VPN between an ASA with a static IP and one with a dynamic IP address. What if you have multiple peers with dynamic IP addresses? If you want, you can land all these VPN connections on a single tunnel-group, but it might be a better idea to use different tunnel-groups. The solution is quite simple, Cisco had to address this years ago when they had remote IPSec VPN clients, you use a Dynamic Cryptomap, and because you can’t have a tunnel group either, you use the DefaultL2LGroup, (this gets used when a specific IP address is not defined). Oct 29, 2012 · Hi Guys, we want to setup a vpn between our central asa5520 and a new branch office asa5505 with dynamic public ip.

Sep 16, 2016 · We have a spare ASA and we are going to create a site to site VPN, despite the fact that the new office IP is unknown or possibly dynamic. Cisco provide a special kind of crypto map for this challenge called a dynamic crypto map and a special tunnel-group called ‘DefaultL2LGroup’ which catches L2L runnels where the peer IP address cannot be Creating Extended ACL. Next step is to create an access-list and define the traffic we would like the router to pass through each VPN tunnel. In this example, for the first VPN tunnel it would be traffic from headquarters (10.10.10.0/24) to remote site 1 (20.20.20.0/24) and for the second VPN tunnel it will be from our headquarters (10.10.10.0/24) to remote site 2 (30.30.30.0/24).

This can also be the public IP of a gateway in front of a downstream router if the upstream gateway is port forwarding UDP ports 500 and 4500. Local WAN IP: Public IP of the USG adopted to the site in which this VPN is being configured. If this USG is behind NAT configure the address found on the WAN interface.

You could take a gamble and configure the IP address manually but as soon as your ISP gives you another IP address, your VPN will collapse. In this lesson, I’ll show you how to configure a site-to-site IPsec VPN but we’ll use a dynamic IP address on one of the ASAs.
Mar 06, 2015 · In this article, we have configured a site-to-site VPN tunnel between a router with a dynamically allocated IP address and a Cisco ASA with a static IP address. The configuration on the router is normal VPN configuration, but we used a dynamic crypto map on the Cisco ASA.
