[SOLVED] 1:1 Mapping - VIP to VIP NAT possible?
I am trying to use 1:1 mapping to NAT from one OPT interface with a VIP stacked on top, to another. Here is the setup;
OPT1: Parent Address 192.168.200.254/24
VIP ontop of OPT1: 192.168.200.10/32, type=IP Alias
OPT2: Parent Address 192.168.89/32 (this is purely here to allow the interface to have VIPs, this addressed is never used)
VIP ontop of OPT2: 192.168.80.254/24
The host I am attempting to NAT to is 192.168.80.100.
My NAT configuration is;
Interface=OPT1, External IP=192.168.200.10, Internal IP=192.168.80.100, Destination IP=*
Pings are possible, but TCP traffic silently dissapears (nothing in packet trace or logs).
Any pointers would be appreciated.
Fixed! Had to change NAT reflection to enabled. Didn't think I needed it as the incoming route was to the OPT1 interface, maybe because it isn't a true WAN interface under the hood?
Hopefully might be useful as another worked example…
