I have several clients using Pix Tunnels for site to site connections. I have one client who cannot route my internal network address space do to an overlap issue. I have tried to setup the nat, but the traffic is not changing to the NAT address.
Here are the entry's I used (the tunnel is working):
access-list outside_cryptomap_1400 permit ip host 64.x.x.5 142.x.x.86 255.255.255.255
access-list inside-outbound_nat3_acl permit ip 10.0.0.0 255.0.0.0 142.x.x.86 255.255.255.255
nat (inside) 3 access-list inside-outbound_nat3_acl
global (outside) 3 64.x.x.5
Any help would be appriciated!
