Right (deep breath).

I have a simple network here, running Netscreen firewall and ADSL. All is normal when coming to the setup, except I'm running a mail server off on of the ethernet ports on the ADSL (got 5 IPs).

Now, my problems start when trying to open up FTP to allow a collegue to connect and drag files back and forth (only connected on demand - and with a software firewall guarding this port).

Problem 1: Firewall went spastic, whining about TCP/IP spoofing (as our server has dual ethernet ports) - one connected to internal switches, other connected to ADSL router.
Problem 2: I can connect fine to the FTP and works like a dream (as any machine internal), but collegue gets a "connection error has occured" message. so whats all that about?

He should be dialling the IP, which should be pointed to out router, which should detect that this IP is running on one of its ethernet ports and allow communication. there is NO link to our hardware firewall for this connection.. so I'm stumped.

Ideas?

Try using a peer-to-peer file sharing application over HTTP (TCP port 80), such as Groove

Firewall... what firewall? http://300zx.co.uk/200sx/ubb/wink.gif

...great idea, but Mac to PC. Bugger.
Can't use ICQ or something simple, as it needs to be 'secure' ish.

Use MSN Messenger Port 18XX?, it has a decryption algorithmn that is available for secure transfer, takes about 20 minutes to configure it, and works quite nicely.

Put Zonealarm on the Pc and have a look at the incoming and outgoing requests. This will help you diagnose if you need to free up come more ports.

And will hopefully tell you if your existing FW is being silly.

Have you disabled Netbt? Try enabling it if you have.
