Multiple NIC cards and gateway

[Armando Angeles]

Hi Everyone,
I would like seek for your assistance on this network setup.

Currently we're using 3CX Phone System 15.6 and running on windows server 2012.
We have Dinstar GSM gateway and Internet SIP trunk.
Info:
3CX Server : 192.168.1.28 (1 NIC Card)
Dinstar: 192.168.1.31
Internet SIP Trunk : 192.168.1.94

Currently the the gateway of 3CX Server is pointed on to 192.168.1.94 where all the calls are working normally.
The issue is on this setup the 3CX Server does not have the internet access because it is pointed on to SIP trunk.

Is it possible just to add additional NIC card to have internet on the 3CX server and used another default gateway?
I read some documents that I need to have one gateway only to work it properly,

Any thoughts and suggestions is really appreciated.

Hello @Armando Angeles

Is it possible just to add additional NIC card to have internet on the 3CX server and used another default gateway?

You can add a second NIC for internet but you need to setup the default gateway on that NIC and set static routes for your provider. You can see the configuration in the link @cobaltit shared.

@cobaltit thanks for the link,
I was not good in the networking concept,

I am lost in the part where I set the static route.

I was able to follow the add route procedure on the link provided below
https://www.3cx.com/blog/docs/network-configurations-supported-3cx-phone-system/ but didn't work.
Inbound / Outbound call is not working if no gateway assign on the NIC card route to SIP trunk.

Any advice and suggestion?
