To build site to site VPN tunnel, one site is using ASA5504, the other site is using LinksysWEV54G. Linksys is doing nating, one public ip address 140.x.x.1, and one subnet private ip address 192.168.1.0 running DHCP. Somehow, we have a 1811 router connect to Linksys via F0/0, and we have machines running 10.10.10.x/24. In the router 1811, can we run nating? Please see below router 1811 configurtion:

interface FastEthernet0
ip address dhcp
ip virtual-reassembly

ip nat inside source list 7 interface FastEthernet0 overload

!
access-list 7 permit 10.10.10.0 0.0.0.255
As you see, there are double nating on one site. Here are my concerns:
1) I have no experience on Linksys. Does 10.10.10.0/24 can pass traffic through Linksys and back to ASA one the other site ideally?
2) Does router 1811 configure ok?
Please help!
