Since the server with ssh and the mail server seem to be the same, try to set the destination IP address of your tunnel to the local address of mail.myserver.com (i.e. 192.168.1.1:25). You may even want to try 127.0.0.1:25 as the tunnel destination. blu ----- Original Message ----- From: <dsimcik () bentley edu> To: <security-basics () securityfocus com> Sent: Thursday, July 15, 2004 1:39 PM Subject: Tunneling SMTP Traffic Via SSH Question
Hi, 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! Cheers, DTS --------------------------------------------------------------------------
