Is there a way to set a Cisco 678 in passive mode?

Re: Passive Mode

Sorry, others might know this, but can you explain what you mean by passive mode?

Consultant? :)

Passive could mean lots of things. Clarification would be nice so we dont guess and waste time by sending the wrong information.

Re: Passive Mode

I can't recall any other meaning for passive except in FTP transfers or maybe the old days of Arcnet. The link is the only example of passive that I have know. That explains exactly what we are trying to accomplish. Sorry for the confusion if any.

We have a client that requires using passive mode to transfer files. With the 678 in place, we can not run in passive mode. We have ports 1024-6000 open on the 678 in order to run passive. The 678 is not running NAT, we have a public IP on the server. We also would like to be able to run passive on a port other than 20/21. Is that possible?

Re: Passive Mode

Regarding passive mode with FTP -- IOS shouldn't prevent this since the router is just passing the traffic through the router, unless you have ACLs, or something set up to alter / filter the traffic. Posting the configs might help us help you. Also, a network diagram so we have a idea of where the server and client(s) are.

Regarding the port numbers, that would on the server / client. Again, the traffic is passing through the router.

As for the previous discussions, passive can mean many things. Examples: Passive interfaces for routing protocols, passive mode for DLSW, and such.
