Can you please clarify whether it is public or private ip, as you have specified: "I have UC520 and router 877 with private public ip address  in our office".

If you can confirm whether you have public or private ip assigned to both ends (UC520 and 877), and whether it is dynamic or static ip address, that would be great.

You can configure either LAN-to-LAN VPN tunnel or Easy VPN tunnel. Here are sample configuration for each scenario:

Static LAN-to-LAN tunnel:

Static to dynamic LAN-to-LAN tunnel:

Easy VPN NEM (Network Extension Mode):

Hope that helps.

Thank you for quick reply, what I meant is public IP address.

in my office the UC520 and Router 877 connecting to each other locally, the internet is on router 877, and in my home I have normal DSL, what I'm going to do is install Cisco VPN client on my laptop and I already have ip communicator, so I think I will go with Easy VPN NEM. Any suggestion
