is there any possibility to limit tcp session count let's say from 3 to = 2 for any port separately? for examples: establishing 3 active ftp sessions from 10.10.10.2 to 10.10.10.1 and = doing transfer via 1 session we have: 10.10.10.1.ftp - 10.10.10.2.57185 - ESTABLISHED 10.10.10.1.ftp - 10.10.10.2.55069 - ESTABLISHED 10.10.10.1.ftp - 10.10.10.2.60589 - ESTABLISHED 10.10.10.1.ftp - 10.10.10.2.59201 - TIME_WAIT 10.10.10.1.ftp - 10.10.10.2.57144 - TIME_WAIT 10.10.10.1.ftp - 10.10.10.2.61237 - ESTABLISHED ---> DATA transfer so, how limit using IPFW any other atempts to establish ftp session = number 4,5 etc... so we could use maximum 3sessions/1 IPaddrs? thnx
