DNAT Problem

mmaaeexx
I have the following problem:

ASG 220 V7.507

I had to implement an VoIP Gateway. This should be available with a public IP.
The Gateway is from internal reachable via http and all works fine. From external (over http) i only get a blank page (with pagename) and in the pages html source the is a error message.


I tried to implement it the following way:

1. added an additional interface with the correct public IP
2. created an Host in definition with the internal IP
3. created an DNAT Rule that redirect all
 to use DNAT to redirect all the Traffic from the public IP to the DMZ
Traffic Source: Internet
Traffic Service: HTTP
Traffic Destination: the IP of the additional Interface representing the VoiP GW
NAT Mode: DNAT
Destination: the Host with the internal IP
4. Packet Filter Rules
Source: Internet
Service: HTTP
Destination: internal IP

I have used DNAT in equal scenaries several times and newer had problems with it.

Any ideas?

thankx for your help

    Make sure your "AVM VoIP Gateway" isn't bound to an interface; it should be >.

    When watching the live packet filter log, put the IP of "AVM VoIP Gateway" in the 'Filter' field to just see the lines relative to the VoIP Gateway.
