The problem is the following:
We have a BR1 connected to its WAN port with an MPLS (static ip cisco 172.40.43.1), its address in the BR1 WAN is 172.40.43.2/25. In the LAN we have the subnet 172.40.43.129/25.
The problem is that requests from the red LAN to the selected proxy server with only one IP that is 172.40.43.2 and no privileges can be given to each IP of the BR1’s red LAN.
Is it possible to do a NAT from the LAN from BR1 to WAN from BR1? for example:
LAN 172.40.43.130 NAT 172.40.43.30 in the WAN network
