NimbostratusMS Firewall Client - BigIP LTM - ISA Server
Hi
We're having problems to set up a Virtual Server for load balancing of ISA Servers.
For the web traffic the virtual server works right but we can't do a FTP session.
We have set up 3 VS
VS:80
pool
ISA Server1
ISA Server2
VS:21 with a profile ftp.
pool
ISA Server1
ISA Server2
VS:1745 for the Firewall Client protocol.
pool
ISA Server1
ISA Server2
We're sure that someone had the same problem before.
Could you give us any help, please?
Thank you in advanced
- For normal FTP connections over 21/20 all you should need to define is the ftp profile.
Are both active & passive FTP failing?
I'd start by taking a close look at a packet trace to see what's actually happening on the serverside flow.

Phillip_Blatzhewe're having a similar issue.
trying to do Active FTP with a vendor.
FTP works great from the LTM.
Works 10% of the time from the ISA servers via a SNAT, not automap.
any suggestions would be great.
Steve_A_130918Can any one confirm that it is possible to load balance the ISA/TMG Firewall Client traffic on port 1745 using a standard F5 VIP
If I try it the connection opens and closes immediately. The ISA/TMG server shows the port 1745 connection, the encapsulated ftp connection and an immediate close on both.
If it is possible, what general configuration do you use on the F% VIP
Thanks
Steve
- Steve_A_130918Just for info, the connection through the TMG, without going via the F5, works correctly.
