Passive FTP failing, F5 send TCP RST after receiving Entering Passive mode from server
Hi Pretty standard setup Passive FTP Control port 10021 Data ports 50251-50500
Configuration
VIP: 192.168.152.8 (Open for all ports) Auto SNAT (interface and pool members on same vlan) Profile Basic FTP Profile Basic TCP client/server profile
Self IP: 10.57.152.6 Pool: 10.57.152.6 (open for all ports)
Problem:
With basic FTP profile, F5 send TCP RST as soon as it receives response of PASV request from server that it entering into passive mode.
If we aremove FTP profile and use basic TCP Profile, it works fine.
TCP Reset from F5 self ip to backend
TCP Reset from F5 to Client
Passive IP: F5 VIP (192.168.152.8) Passive Port 50252 Passive IP NAT: True
Thanks Syed
