Pix port 're-mapping' assistance
Posted on 2007-07-31
We have a client who runs an application that comes through the firewall (Cisco Pix 506e) on port 4444. It has been working for years with no issues until two of the local service providers blocked that port because of a blaster worm and now anyone on those two carriers cannot access the system. This is a medical client who provides imaging to remote offices.
We already tried to get the software vendor to change their listening port but that cannot happen. We will need to make the Pix "re-map' so when you hit the outside IP address (statically mapped) on port 2222 it will 're-map' the incoming packets to port 4444, hit the server, and when the server sends the response back out to the internet and "re-maps" it back to port 2222 when it is delivered to the client.
I'm pretty good with the basics on the Pix and cannot seem to get the commands correct on my test Pix box...
