 Re: How to configure site-to-site VPN between networks with same IP addressing scheme
as mcnallym said set up the NAT on you side so all traffic from your internal network to the other party vpn network is NAT-ed.
Other party should set your NAT-ed network as "encryption domain" for you gateway and not your internal network.
So, on your side
NAT: int_net->remote_vpn_net->source(new non-conflicting net)->dst original
On remote party side they should define:
Your gateway as VPN peer
Encryption domain/ID - your new non-conflicint net you are hiding your real net behind. |
