deploying 877 with security

hi

using 877 i will use ADSL connection for internet from my branch.at central site i have 1841 and PIX515E, i want to implement VPN.using VPN client software all the users can work.but if i want to go for site to site vpn, there is a small problem.for my ADSL connection i will not get a static public IP from service provider.IP on my ADSL interface will be a DHCP address from my ISP's pool.

so in this case lets say after 1 month IP of my ADSL inteface changing in this case

is there any way to dynamically update the central site regarding the IP change.

i'm bit confused here .i will appreciate all the inputs.

Thanks & Regds

Binoy.

Re: deploying 877 with security

In case of a site to site VPN you can use a Dynamic Multipoint VPN (DMVPN) solution. This is a hub-and-spoke design where the spoke could have a dynamic ip address.
