    Adtran 908e Behind NetVanta 4430 Firewall

    jamesw New Member

      Customer has a gig internet connection and wants the 4430 as the firewall for everything. Adtran 908e (esbc enabled) sits behind it with a private IP. 908 is SIP to PRI for a PBX. I have the 4430 sending all traffic from SIP provider to the 908e. Calls establish but there is no audio. in the 908e I had to add the 4430's public IP as outbound-proxy secondary, otherwise I would get SIP CLDU errors and calls would not go through. Currently has only 1 public IP address and doesn't want more. Anyone have any configuration suggestions. Sorry this is so brief please let me know if you need further info.
