Need assistance setting up PAP2 (voip) on the DMZ [FIXED]

ck42

I have a ViaTalk voip adapter and want to configure it to be setup on the DMZ.

I have a functioning system and have added the DMZ interface.
I've setup the DMZ on a separate subnet (internal LAN is on 192.168.0.0/24 and DMZ is on 192.168.1.0/24)
Under the DMZ rules, I've added:

Rule to allow the DMZ outbound access using any protocol and to any address (Source: DMZ net - everything else is ANY)
Rule to allow inbound UDP ports 5060, 10K-20K destined to the static IP address of the voip adapter (Source/Port ANY, Destination: IP address of voip adapter, Port set for 5060 and 10K-20K)

I've also setup in NAT 2 entries for port forwarding. These are for the two port ranges mentioned in #2 above.
They're configured as such:

Interface: WAN
Protocol: UDP
External port range: As mentioned in #2
NAT IP: IP address of the voip adapter
Local Port: Again, same port number or range mentioned in #2

In the NAT section, under the outbound tab, there is an entry for:

Interface: WAN
Source: the DMZ's network range
Destination: Any
Translation: N/A

So, as far as I can tell, this should be working.
Just to be sure though, I placed the voip adapter on the LAN subnet and got it to successfully connect.
But, when it's configured and running on the DMZ, it won't connect.

What am I missing? ???

[EDIT] Looks like I need to set a static port in the NAT 'Outbound' section.
I simply took the entry that was already there and set the 'Static Port' option to YES. Then changed the radio button to the 'Advanced Outbound NAT' option. Looking at the GUI of the adapter, it's still not connecting.

[EDIT2]
Never mind. Got it working. I had previously, temporarily while testing, disabled the rule that allowed the DMZ outbound to anything….before I discovered the Static Port config that I was missing. Once I re-enabled that DMZ outbound rule, it looks like the Static Port setup was able to properly take effect.
