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
