Hello there

We need to migrate to a new subnet but still NAT through the old one.

What I mean is that we are removing a router that used to do the WAN and just using a single router now.

So we need to nat from external router WAN to internal router WAN to internal router LAN all inside of a DrayTek 3910

is this possible?

DrayTek are telling us that if we add the /27 WAN as alias' to the WAN it will somehow route them through in both directions.

I hope that they are right!

We just got BT to delete the 81. subnet in the end so it routes straight through with exactly the same settings as it had before.
