Scenario: IP addresses comp1=xx.xx.xx.1 comp2=xx.xx.xx.6 comp3=xx.xx.xx.12 comp1 and comp3 run FBSD 4.9 stable comp2 runs FBSD 5.1-RELEASE comp1 is a bridging firewall using ipfw A: comp2# netstat -n |grep xx.xx.xx.1 tcp4 0 0 xx.xx.xx.6.54953 xx.xx.xx.12.3551 TIME_WAIT tcp4 0 0 xx.xx.xx.6.54952 xx.xx.xx.12.3551 TIME_WAIT tcp4 0 0 xx.xx.xx.6.22 xx.xx.xx.1.1233 ESTABLISHED B: comp2# netstat -n |grep xx.xx.xx.1. tcp4 0 0 xx.xx.xx.6.54954 xx.xx.xx.12.3551 TIME_WAIT tcp4 0 0 xx.xx.xx.6.54953 xx.xx.xx.12.3551 TIME_WAIT tcp4 0 0 xx.xx.xx.6.22 xx.xx.xx.1.1233 ESTABLISHED C: comp2# netstat -n |grep xx.xx.xx.12 tcp4 0 0 xx.xx.xx.6.54957 xx.xx.xx.12.3551 TIME_WAIT tcp4 0 0 xx.xx.xx.6.54956 xx.xx.xx.12.3551 TIME_WAIT Actually..I see the same output on a cygwin machine behind the comp1 firewall. So, does this have something to do with the bridging as I do not see the same behavior on another FBSD machine that is on a different network? __________________________________ Do you Yahoo!?
