Port Forwarding with RB2011UiAS + RB750

Wed Jul 03, 2019 2:23 pm

Hello,

I am trying to open couple ports for a server at an office.

The network setup is: Optic internet comes into a converter. An ethernet cable goes to RB750 slot1. From slot5 ethernet cable goes to a phone. From slot4 ethernet cable goes into RB2011UiAS (eth1).
My NAT setup:
0    ;;; HAIRPIN NAT
      chain=srcnat action=masquerade src-address=192.168.2.209 dst-address=192.168.2.209 log=no log-prefix="" 

 1    ;;; default configuration
      chain=srcnat action=masquerade out-interface=ether1-gateway log=no log-prefix="" 

 2    chain=dstnat action=dst-nat to-addresses=192.168.7.30 protocol=tcp dst-address=192.168.2.209 in-interface=ether1-gateway dst-port=00000
      log=no log-prefix="" 

 3    chain=dstnat action=dst-nat to-addresses=192.168.7.30 protocol=udp dst-address=192.168.2.209 in-interface=ether1-gateway dst-port=00000 
      log=no log-prefix="" 
note: I removed port numbers

From my understanding the RB750 gets WAN ip and creates a sub network (192.168.2.0/24) that has the phone and the RB2011UiAS. Then RB2011UiAS creates another subnet (192.168.7.0/24) and if I want to open the ports, I most likely need to open the port at RB750? To do that, I need to connect a PC directly to RB750 or can i connect to it through the network?
