I've been experimenting some with using relayd to load balance incoming smtp, pop3 and imap and it seems to work wonderfully with relays, unfortunately I cannot use redirects since I need to direct to different server pools depending on the originating source IP. The only thing preventing me from deploying this is I need the connections to be transparent.
OpenBSD 4.4 introduced a transparent key word, but for the life of me I cannot get this to work. If configured as outlined in the man page, relayd fails to start complaining about an interface missing from the configuration. If an interface is specified, relayd starts but connections time out immediately: relay maildelivery, session 4 (1 active), 0, 66.159.122.2 -> 10.10.19.4:25, connect timeout When I trace the packets, I can see the connection being made to 10.10.19.4, and a reply issued, but the time out still happens, so I'm at a complete loss. Has anyone been able to get transparent relays configured? I'd appreciate any help anyone can provide. On another note. One thing that would be nice to see in relayd is the ability to specify a source ip or table in the redirect definition as that would eliminate the need for a relay for this configuration.
