I'm curious, besides spamming, why would you want to do this? How much outbound SMTP does it take to make it "cheaper"? -- John Brooks Email: john@stlbsd.org -----Original Message----- From: owner-freebsd-isp@FreeBSD.ORG [mailto:owner-freebsd-isp@FreeBSD.ORG]On Behalf Of Blake Crosby Sent: Wednesday, November 14, 2001 11:31 PM To: freebsd-isp@freebsd.org Subject: Source Based Routing I'm sorry if this is off topic, nor is directed at the wrong list. I have cable and DSL. I want to use cable for most of my traffic, as it is cheaper. But I want to use DSL for incoming SMTP connections, because DSL provider allows me to run an SMTP server (cable provider forbids it) and gives me a permanent IP. I don't want to have to use someone else's mail server as a gateway to mine. The cable provider will not let me send packets back to the Internet with the source address of my DSL IP. This causes a problem when a remote site tries to connect to DSL IP port 25, but the reply packets get sent out the default route of cable. How can I make packets for a TCP connection from the DSL IP, go out the DSL interface, no matter what the IP of the other end of the TCP connection is? There used to a be a FreeBSD port called brouted which I think might let me do it, but I can't find it anywhere now (apparently it had security flaws).
