I have an 11503 and I am trying to load balance sftp servers behind it. not sure why it's not working.
here is the content rule:
content test_sftp
add service www1_sftp
add service www2_sftp
port 22
protocol tcp
balance aca
advanced-balance sticky-srcip
vip address 172.17.0.248
active
here are the service rules:
service www1_sftp
ip address 172.17.0.27
protocol tcp
keepalive port 22
keepalive type tcp
active
service www2_sftp
ip address 172.17.0.25
protocol tcp
keepalive port 22
keepalive type tcp
active
couple of questions:
1) do I need to set up a source group like I would have to for ftp? Does the return traffic from the servers need to be NAT'd back out as the VIP?
2) the content rule and service rules are all set for port 22 only....is that enough ports open for the control and data channels? I think sftp uses port 22 for both.
Any assistance would be greatly appreciated.
Thanks!
