How to create an iRules that allowing multiple ports on a single VIP IP address. Example i have 1 VIP 10.10.10.10 with port range 50000-60000 for SFTP active, with pool member 20.20.20.20 port: 50000...
Additionally with the same i-rule can you change your VIP to performance layer 4 instead of standard and then check do a tcpdump to see whether the VIP is doing a 3way handshake.

NimbostratusHi Maneesh,
do we need this iRules
if{([TCP::local_port] > 50000 and [TCP::local_port] < 60000)} { permit elseif {[TCP::local_port] == 22 }{ permit } else { Drop request drop }
or this one
when CLIENT_ACCEPTED {
if{not(([TCP::local_port] > 50000 and [TCP::local_port] < 60000) or [TCP::local_port] == 22) }{
drop } }
