Thanks for that. The only issue with his setup is that he does not mention any Voip/SIP issues. Because of that I am assumming he does not need/use Voip. For us, the Archer has the hidden configuration for SIP connection/translation etc. It then broadcasts this out to the four LAN ports (two of which are connected to ATA4 devices to give me FXS inputs to our phone system. Unfortunately, this appears to be the only option for us as we were advised that we could not be provisioned 6 real SIP trunks to go directly into the SIP interfaces on the PBX but had to convert to FXS. The third LAN port (connection to the LAN switch) means that because the Voip traffic is being broadcast out, not only do the two ATA4 devices receive all Voip traffic (dropping that traffic not intended for them) but also goes into the LAN switch where and is then dutifully ignored by all our LAN devices. What I am trying to do is use the Kerio Control software to route all Voip/SIP traffic to the IP address of the Archer and any other traffic to the LAN, reducing the congestion on the LAN. Currenlty I can easily place the Kerio Control box on the Archer but when I try the reverse the Archer is not happy to be the second device (even though it is receiving the exact same traffic).   I will sort it one day :-)   ...
