Unable to remote into PBX behind Sonicwall TZ-190

Unable to remote into PBX behind Sonicwall TZ-190

(OP)
I am trying to set up a few firewall rules in order to gain remote access to a PBX behind the firewall.

The logs state as follows:
4 12/23/2015 09:15:43.208 Notice Network Access Web management request allowed 100.1.214.132, 23300, WAN (admin) 72.248.20.166, 443, WAN TCP HTTPS
5 12/23/2015 09:14:06.736 Notice Network Access TCP connection dropped 100.1.214.132, 23185, WAN (admin) 72.248.20.166, 35300, WAN TCP Remote PBX 35300 TCP

The TCP connection on port 35300 is being dropped. I am unable to find out why yet. I have the following configurations:

Address Object for my Private IP address
Zone Assignment: LAN
Type: HOST
IP Address: xxx.xxx.xxx.xxx

Service Objects for my port TCP and UDP 35300
I created a service group and added the service objects and named this 35300 services

I created a NAT policy as follows:
Original Source: ANY
Translated Source: Original
Original Destination: WAN PRIMARY IP
Translated Destination: PRIVATE IP (Address Object)
Original Service: 35300 SERVICES (Services Group)
Translated Service: ORIGINAL
Inbound Interface: ANY
Outbound Interface: ANY
Enable NAT Policy

I have an access rule created for WAN to LAN
From Zone: WAN
To Zone: LAN
Service: 35300 SERVICES
Source: ANY
Destination: WAN PRIMARY IP
Users Allowed: ALL
Schedule: ALWAYS ON
Comment:
Action: ALLOW


The TCP connection to 35300 is dropping and I would look to my access rules as the reason.
I have the same issue even if I use the Public Server Wizard.

Anyone have any ideas?

Hi-- Did you ever have any luck sorting this problem out? I have the same issue and would love to know what the problem is!
