if we have overlapping IPs in in the site-2-site VPN between on-prem to azure cloud. can i do the following.

virtual network (compute VM)--->nat gateway---->vpn gateway--->ipsec tunnel--->vpn gateway (on prem).

this way, we would avoid the overlapping IP issue.

please note that im the on-prem connecting to extranet party on azure, so i dont have control in rebuilding their environment. i'm just seeing if they can do this. otherwise, ill end up doing both source and dest nat at my end.

    Do you need the NAT gateway between the VNet and the VPN gateway? Can't you define NAT rules on the VPN gateway directly as described in the article below?
