Do transparent / split tunnels act as a DHCP server?

We have some IP phones at a remote site which has limited bandwidth (currently connected to a RED50 using a standard / split tunnel)

I am trying to setup a QOS rule so the phones always get a reserved chunk of the bandwidth as the site often maxes out their internet connection which is dropping out calls (I have done this in the UTM and it works fine at the main site).

However due to the IP phones being a bit rubbish at the remote site they are connecting to our public facing IP of the phone system rather than it's internal IP so at the moment the QOS rules don't  apply. 

Am I right in thinking that the only way to force traffic for phone systems public IP through our local network would be to change the tunnel to Transparent/Split  and then setup a rule to make the traffic for public IP of our phone system route through local network? this way the QOS rule would come into effect?


Am I also right in thinking that by changing over to Transparent/split this will stop the RED from acting as a DHCP server and I will have to find another way to issue IP addresses out to devices at the remote site?

  • If you don't get the call quality you want with Sachin's recommendation, I'm afraid your problem is too complex to get handled here.
