question regarding creating a site-to-site VPN between an ASA 5505and a VPN 3030

HI, all

I've been hitting a weird problem when attemping to create a site to
site VPN connection between an ASA 5505 and a VPN 3030. For some
reason, the IPSEC tunnel gets created, and I can see packets
encrypting, but I never get packets back, and thus no packets get
decrypted.

The firewall config is very basic. There is no split tunnelling, and
the access-lists are set up so that any traffic going from the local
subnet (say 192.168.1.0) to the remote subnet (say 192.168.10.0) will
trigger the tunnel to form. The firewall is connected to an ADSL line,
and the Internet connection seems to come up no problem

On the VPN 3030 side, we have a static route to the subnet for the asa
5505 with the public interface being used as the next hop. The VPN
3030 listens to RIP routes from the rest of the network, but does not
send routes. All other routers behind the 3030 have a static route for
the subnet on the ASA 5505.

Can anyone tell me what are the major steps required to make a site to
site connection work in this scenario? I've tried using Cisco's
manuals, and they should work, but it doesn't.

Thanks!

 

As per the issue..

I understood below scenerio:

ASA 5505 <------VPN-TUNNEL------> VPN 3030

Is ASA NAT the inetrnal ips when it hits VPN 3030?
R u able to see logs/hits on VPN 3030?
Can u post the logs if u find any..
