I’ve a buyer who I present a router / default gateway to the web for. On their community they’ve a MPLS coming in with a router managed by a third get together. The third get together system has LAN IP 172.20.0.1 and my gateway is on 172.20.0.125.
They’ve a server on 172.20.0.35 and so they need to have the ability to speak to this, over the MPLS hyperlink, from a distant web site. The .35 server is at present utilizing .125 because the default gateway and I can not add static routes to the server.
My router has a static route for the distant finish of the .1 hyperlink (172.21.0.0/16) so they can ping my router from the distant aspect, however they don’t seem to be capable of ping the server on .35.
They’ve requested me to setup a NAT for a brand new IP .36 and to have my router carry out NAT from 172.20.0.35 to 172.20.0.36 and the reverse in order that the comms from the 172.21 community will hit my router after which be NAT’d to the .35 handle.
Will this work? I’ve by no means tried NAT from Subnet A to Subnet A earlier than, solely totally different subnets.
