I have an application, running on linux box with kernel 2.2.19, that attempts
to establish connection to an LDAP server. However in response to SYN-ACK
from LDAP linux sends RST. The LDAP server is behind several routers, and
according to a customer, when LDAP and linux are in the same subnet everything
works fine.
Can someone please explain what's wrong. Tcpdump capture attached. Thanks a lot.
Felix.
