I see that I can disable ident (113) thru my linksys router AFTER connecting to IRC (on DALnet anyway) and the port is stealthed according to dslreports and grc.com. This only takes a few seconds to disable thru the browser and it's more secure.
That's true...but if you use IRC quite a bit....that's not a real feasible thing to do. Maybe, a firewall (software...cheap and easy, or even as firewall appliance, not so cheap, but very secure!), and only allow you're IRC client access to the port...that will certainly cut down on any threat!
