i want to create site to site vpn between two sites but both the sites having dynamic ip.my question is ,is it possible to create site to site otherwise any other way is there ..if site to site is possible send any documentation
No you cannot make a site-2-site vpn with dynamic IPs on both sides. Dynamic crypto maps don't allow you to initiate connections, if both sides have dynamic crypto maps, who will initiate the connection?
You can setup a remote-access VPN. Preferably register the VPN server IP with dyn-dns. Then just enter the dyn-dns hostname of the VPN server in the Cisco VPN Client. Just make sure you are running a newer version of the Cisco VPN Client.
thankyou for ur reply
i am not asking about remote vpn client...
it is possible to create site to site vpn using these dynamic dns hostname..
because i am having both sides dynamic ip.
if it is possible give me some example
I already told you that you cannot. From my original response:
"No you cannot make a site-2-site vpn with dynamic IPs on both sides. Dynamic crypto maps don't allow you to initiate connections, if both sides have dynamic crypto maps, who will initiate the connection? "
Please rate if helpful.
i configured remote client in asa 5505 and everything working fine.remotely connecting but the ip address and gateway is same..
for example i assign a pool 192.168.1.10-192.168.1.20
the ipconfig remotely
ip addrss 192.168.1.10
so i am not able to access anything.
That default gateway is normal. Don't worry about that.
'acesss anything' what do you mean? Did you check the encr/decr on the ASA and the VPN client?
What is the point of defining a 'permit any' ACL and then doing a 'tunnelspecified'? Just do a "tunnelall".
Is phase 1 and 2 UP after the client connects? Do you see encap/decap?
show crypto ipsec sa
setup a DMVPN using NHRP at the hub site, which will keep track of the current global IP address at the two spokes, and they will be able to dynamically form tunnels between them, and even if the address changes, those updates will re-register with the NHRP server. That's assuming this is IOS-IOS VPN.
What devices are you using ?
You can have One device with dynamic IP using easyVPN Server/client feature for sure, and I think you can have both with dynamic IP by using a DNS name instead of IP to define ezVPN server on client.
So you can configure one asa with remote vpn as described here:
and enable network extension mode:
group-policy VPNGP attributes
and on the other side, confiugre your asa as a easy vpn client. Asa server should have a DNS pointing to its IP, you can use dynamic DNS features:
vpnclient mode network-extension-mode
vpnclient vpngroup VPN_Tunnel password VPNPSK
vpnclient username xauthuser password xauthpwd
vpnclient server asaserver.mycompany.com
Network extension mode permit that user behind the asa acting as client access and be accessed through the VPN Tunnel. Default mode (client mode) will make the client asa NAT/PAT the inside hosts so they appear as being the asa.
If that solves your pb, please mark thread as resolved and/or rate it.
