My first guess would be to check your outlook settings, like everyone else suggested first (host: 127.0.0.1, port 3225). If that doesn't work, check putty and make sure the port forwards are *saved* properly. I typically don't use putty for SSH port forwarding, but when I did, I remember that you had to make sure the session you were connecting to had the forwards saved into them for it to work. If they were not saved, just entered and applied, then the port forward didn't work. -b On Fri, 16 Jul 2004 14:12:38 -0600, Dan Daggett <ddaggett () gmail com> wrote:
My apologies if this is a dumb question -- I'm attempting to forward port 25 (SMTP) over SSH via Putty to an off-campus mail server. Here are my connection parameters: Session> Hostname (for SSH): mail.myserver.com Port: 22 SSH > Preferred SSH protocol version: 2 Tunnels> Forwarded ports: localhost port 3225 to Destination mail.myserver.com:25 When I try testing the connection in Outlook it returns an error saying that Outlook cannot connect to the server. I know that out our outbound WAN connection is blocking outbound port 25 traffic and I was hoping that I could get around that via SSH forwarding. Firewalls can't peer into the tunneled packet headers, can they? Help!Did you change the outgoing mail port in Outlook to 3225? --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute.
