As we moved to another firewall with fewer connectors (PIX 515 -> ASA 5510), I had to prune the network infrastructure a bit, so one of the subnets had to go. Now we've got one piece of hardware that still insists on reaching one of the servers via a hard-coded ip address. It might be a while until I get an update, so I need some tricks to work around that.
Now, as we were waiting for the new firewall, I had a temp Linux server set up, where I could forward any connections originating from one machine to the new address. Somehow I can't manage to do this over the ASDM.
So basically I need the following setup: Treat address old-ip (removed) as new-ip (new address), preferably only on machine rogue-client.
This is on a ASA 5510, IOS 8.2, ADM 6.3.
