Voip VLAN behind RED 15

Predrag Milenkovic

Hello!

We are running UTM 210 on central location and RED 15 on remote locations. UTM Eth0 port is in bridge with RED devices. Recently we decide to start to use local Telco VoIP services.

They gave us their L2 switch with 2 VLANs predefined: 2629 for voice and XXX (I cannot recall now :)) for Internet. On our side we have created tagged VLAN 2629 on all switches on central location as well as on remote locations. On our core switch we have defined port 26 as VLAN 2629 untagged and connected it to Telco switch ("Voice" port).

Telco gave us just VLAN IDs - IP phones are using autoprovision and after we manually set VLAN they are getting IP addresses from Telco DHCP server as well as other settings.

On central location everything is working just fine - IP phones are getting IP addresses and other settings and they are working properly.

On remote locations IP phones cannot get IP address - so they are not working.

This is our layout:

What we did wrong?

Thank you in advance

    Hi Predrag and welcome to the UTM Community!

    The "trick" described by Charmacas is the only solution I know with the RED 15.

    As for the RED 50, an SG 115 with a Network Protection is more flexible and costs less than a RED 50 with warranty extensions.

    Hey ,

    sorry for bothering you but i dont want to open a new thread because my question ist similar.

    The described "trick" only works with Standard/Unified and not with Standard/Split mode, or am i wrong?
    I am asking because there are several statements over the years. VLans weren't supported in Standard/Split but worked nevertheless over the tunnel at least until August 2017 (for example). I know the Note of the Manual.

    Do you know if i clould use vlans through an RED50 tunnel in Standard/Split, provided by an switch (not the red itself) or is it restricted as described in the Knowledgebase?

    Thank you

    Hallo willow,

    I don't know, but I suspect that you're correct.  Instead of RED 50s, I've used UTM 120s and now SG 115s, so I've never seen one!  Over a six-year lifetime, an SG 115 with Network Protection is less expensive than a RED 50 with warranty extensions.

    Cheers - Bob
