port forwarding to two GS devices on the same network

[sotiris]

Hello all,

I am using a GS500,configured with NAT and the appropriate port forwarding to my firewall,using the default Polycom ports for RTP(3230-3261).

Now, i would like to place a second unit to another meeting room under the same network,with the same public IP.So i have to use other RTP ports,but what about 1720 and 5060 ports?

I can't change the setting from codec's web interface,so how can implement this scenario?

Regards,

Hi @sotiris,

you can´t use two GS500 behind one public IP without a gatekeeper like Polycom VBP. How should your Firewall/Router differentiate the calls and forward it to the right GS500?
