I have an issue which i need some help about. I have users using the Cisco VPN CLient to connect back to our office network when they are out of of the office. The IP Address issued to them by the Cisco Pix when they tunnel in is 192.168.16.x . However , our internal network is using the 192.168.15.0/24 network. They have no issues accessing the internal resources but when they need to access our other servers which is connected via a MPLS line , they are unable to as the ACLS on the MPLS line only allow ip addressses from the 192.168.15.0/24 network to pass through. Getting the counterparts to edit the MPLS will be a total hassle. Therefore is there a way to translate the VPN IP address 192.168.16.x into a 192.168.15.x IP once the users are connected.
