im searching for solution to my problem with vpn connection.

On one site i have ASA on other site is a dsl line with d-link router and cisco 871 router. Scheme is in attachement.

I need to setup site-to-site ipsec VPN between my cisco 871 (ethernet WAN/LAN) and ASA.

I can`t switch D-link to transparent mode (not supporting). Is there a way how to create a VPN connection?

Refer to this article:

In addition to what's explained in the article, you will be using NAT-T (nat traversal) for IPSEC. It allows for the dynamic client to sit behind NAT. Note that the PIX configuration in the article does not refer to the public or private IP of the client IOS router.

ASA has NAT-T enabled by default

IOS has NAT-T enabled by default since 12.2(13)T
