Hi,
I’m doing something a little un-conventional. We’re trying to NAT a block of addresses coming into the router back out across the internet to another block of addresses. I have been able to get the router to dstnat the packets (I can see in the packet sniffer, it creates a packet copy with the new address) but they won’t route out any of the interfaces. I have set a static route it’s a redundant but specific route to the IP block I’m trying to reach. Still the 2nd copy or NATed packet isn’t seen on any of the interfaces, I’ve tried changing the static route to go through each of the interfaces but nothing appears.
We need to do this since we are moving our servers and want to pre-configure the new address space in DNS and temporarily NAT the arriving packets back to the web servers in the old block till after the move. Can’t use a tunnel as we will loose distant block when we move and will reconfigure the remote NATed block to become a private block behind this router after we move.
As a test I was able to make this work with a DD-WRT/Linksys router without problems, but not sure it can handle 25Mb of continuous traffic, although the NAT router will only handle web requests, servers will answer directly.
Thanks,
Dave
