IPSec VPN Connectivity between Cisco IOS Router GNS3 and

When 1:M NAT for site-to-site VPN is configured, the MX will check the source IP address against a address translation table. When 192.168.128.44 attempts to send traffic to the web server across the VPN, the source IP address is evaluated to be contained within the local subnet of 192.168.128.0/24, which requires a translation to be performed.
