I have a request from our client to restrict the access between the DMM and the DMPS only to the usable ports.
So i ended up to the following ports: 20,21,80,8443,443,7777,6666 all TCP ports initiating connection from the DMM to the DMPS.
I have applied the access list but it seems that i cannt push/change content to the DMPs but on the contrary, i can perform tasks on them.
Am i missing any ports here or is it using dynamic ports?
Thanking you all
Solved! Go to Solution.
I'm resuming this conversation because i'm not able to access the DMP by gui after applying the access list
So, i have permitted the communication to be:
From Admin Pc to DMPs: ports 80 and 443.
This enables me to navigate to dmp,accept the ssl certificate and login to the DMP.
Then,all i get is a blank screen on the web browser (both ie and mozilla).
Do i need to permit anything else apart from these 2 ports?
Thank you all.
Remember the TCP traffic is 2-way.
Ports 80 & 443 are correct if you apply the access-list as
in & out.
The Admin device is going to use the DEST port as 80 or 443
with a SRC of something like 58xxx. The DMP will respond
with a DEST of 58xxx and a SRC of 80 or 443.
It sounds like you are allowing 80 & 443 out but not back in...
You be able to turn on debugging on the Router for access violations
and you see what ports are failing the access list.
I hope this helps..
IT was a flash player issue!
Flash player was not installed on that computer.
The access list is testes (as stated before) and is working ok!
