We are trying to bring up a L2L VPN to a vendor. The vendor's IP addresses overlap with one of our internal subnets. The vendor claims that they cannot apply a NAT on their side. Is there a way to configure NAT on my side to NAT the remote host? I tried creating a static entry
static (inside,outside) globalIP localIP subnet
The NAT seems to work, at least according to the xlate table, but I cannot bring up the tunnel.
1) will this actually work?
2) how should I define "interesting" traffic? Using the remote NAT or the remote real IP?
Thank you.
