Enterprise firewall recommendation

[gtinet]

Hello All,

Our 3CX server is in-house, current version, and running on Server 2019. We've recently started experiencing one-way audio/no audio on incoming calls. Everything I read suggests that our office firewall/NAT device may be causing the problem. We currently use Sonicwall and will be replacing it soon. I'm looking for suggestions on what I should replace it with. Another Sonicwall? A different brand? SBC? I have no desire to move our config to the cloud or use hosted.

Thank you,
Kevin

Go with Ubiquiti, Fortinet, Watchguard, even Cisco Meraki. Juniper is good as well.

SonicWall has many issues with 3CX for some reasons. I see a lot of those.

Do you have legal reasons to be on-premise? Cloud is much easier and the SBC fixes almost all the network issues.

pfSense. You could do an appliance from Netgate or a VM on your own hypervisor.

Kevin,

I use SonicWALL exclusively for my deployments. What SonicWALL model and firmware are you using? Also gather the info requested here: https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

I've been using Mikrotik CCR Series with 2 3cx installations for about 9 years. Both were under 100 users in the building.
