I have a remote site at IP address xx.8.140.226 currently using a Linksys to VPN to an ASA 5505 (at IP xx.60.101.154), in a lan to lan connection. I wanted to replace the Linksys at the remote site (xx.8.140.226)with a Cisco Secure Router 520. I used the Cisco Configuration Assistant to set up the VPN on the 520, but there weren't many options. When I plugged it in all set up, everything worked fine but the VPN. The ASA 5505 at the central location xx.60.101.154 keeps giving errors in its log. I attached the running configs of both devices, and also the errors the ASA 5505 is giving when the SR 520 is trying to connect to it. Any help would be greatly appreciated. Any questions let me know and I will reply right away.
