Hi, folks. I'm experimenting, trying to setup a situation where connections to port 25 on machine A are forwarded to port 25 on machine B. I've read the ipfw manpage and it looks as though what I'm doing is correct. The IPFW rules on machine A are: 00100 fwd machineB tcp from any to any 25 65535 allow ip from any to any And there is a sendmail listening on B's port 25. But when I telnet to machine A's port 25, all I get is a perpetual "Trying" message that just sits there. Machine A's kernel has the following IPFW options built-in: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=30 options IPFIREWALL_DEFAULT_TO_ACCEPT options IPFIREWALL_FORWARD Any clues as to what I'm doing incorrectly would be greatly appreciated! -- John ------------------------------------------------------------------------- | Beneath the noble bird, between the proudest words, | jfox @ mind.net | | Behind the beauty cracks appear | Sysadmin, | | Once with heads held high they sang out to the sky | InfoStructure | | Why do their shadows bow in fear? | Ashland, OR USA | -------------------------------------------------------------------------
