LDAP send RST after got FIN from F5 , but if bypass F5 it's work correctly

Hi

 

I've problem about LDAP server send RST+ACK after F5 send FIN+ACK to LDAP server.

 

Is this expect behavior? because if i connect ldap server directly, LDAP server will send FIN normally (no RST+ACK like when connect via F5 virtual server)

 

as below picture

 

IP (.18.12) is LDAP server send RST+ACK after it got FIN+ACK from F5 IP (.18.85) is F5 float IP ... we do snat automap IP (.18.91) is F5 LDAP virtual server

 

Thank you

    Hello kridsana,

    Based on your capture it doesn't seems that the F5 is doing something wrong because it is only forwarding your client and servers trafic.

    Could you print the config. of your VS using the following command 

    list ltm virtual vs_name

    Regards
