Question : seesion is not establishing to desire ports

hi expert, some guys in our data center can not establish connection with servers on the desire ports,
from network side i check that i can ping and remotdesktop their servers but they need to telnet
their servers on specific ports but when they do telnet they are not able to connect with the servers on desire ports.
 firewall is working on any to any permit policy and i also check the core switch there is no access list blocking the any traffic.
telent and other ports services are enabled on their servers that they want to access.
please check the attached image.

Answer : seesion is not establishing to desire ports

you may want to check the mapping on the firewall whether it forwards the request to the correct IP or not. When i say this i mean that Firewall has a rule to forward the request to correct IP.
How you are connected to your Server?
