DMP 4400 can't keep alive in DMM

[hnghia18s]

Hi all!

I'm deploying DMS with 1 DMM v5.2 and 1 DMP 4400 v 5.2 like:

dmm(192.168.2.3/24) -> (192.168.2.1)router(123.30.24.246)-> internet -> (113.170.138.59)(ADSL modem)(10.185.254.242) -> DMP4400(10.185.254.242)

I open nat port 20,21,22,8080,6666,7777,80,8443,443 on ADSL modem and Router

DMM only see DMP about 5s and DMP go down

I can't send any asset from dmm -> dmp

Plz help me to fix this

Hi all!

I fixed this problem by adding nat overload in router.

But now i can't play assets from dmm to dmp.

Anyone can help me which ports must open to play assets from dmm to dmp? or any ways?
