Cisco ASA 5505 VPNs from two remote offices to one central office. Remotes are DYNAMIC IPs

I am charged with creating VPNs between two remote offices that are on Dynamic IPs and a central office on a static IP. All three locations have Cisco ASA 5505 devices.

Main office:

WAN: 216.176.xx.xx
LAN: 192.168.1.x (ASA is 192.168.1.254)

Remote Office 1:
WAN: Dynamic
LAN: 192.169.1.x (ASA is 192.169.1.1)

Remote Office 2:
WAN: Dynamic
LAN: 192.170.1.x (ASA is 192.170.1.1)

Below are the working configs from the Central office and one of the remote sites.... I had tried to use some VPN configs from a working PIX system I created a number of years ago, but failed, so ignore that part of the config =)

Oh, and it would be a HUGE help if the Easy VPN was not needed, as I currently do not have a way to configure the ASA's using the GUI, only SSH in for now.

As always, thank you all for your help!!!!!!

John

I'm sorry, I have been working out of the office this week and I have not even had a chance to look at this.... (also sick from a cold... ugh!!!)... I will give it a gander and see how that helps!

Thank you,
