Hello! I'm trying to set up a box as round-robin TCP proxy. Of course, I'm trying to do everything on kernel-level. This simple setup rdr on sk0 proto tcp from any to any port = smtp -> <outbound> port 25 round-robin should work. At least, I thought so. However, attempt to connect to port 25 yielded unexpected result. pfctl -s state shows self tcp 89.108.94.212:25 <- 89.108.94.91:25 <- 89.108.94.211:56975 CLOSED:SYN_SENT connection never established, and no IP packet ever sends out to 89.108.94.212:25 I don't understand this thing. Maybe someone can point me to my error? (firewall rules a quite permissive, in fact, they are pass in quick and pass out quick for all interfaces. attempt to telnet to port 25 outside works ok) Alex.home | help
