Hello,
Can anyone please recommend me some suitable hardware for my application? I am looking for something that can run OpenWRT and is strong enough to handle OpenVPN with some simpler VoIP traffic (I think G.711 codec is 128 kbit/s) and firewalling. I have a desktop VoIP phone that is supposed to connect over internet to a phone company server that offers paid SIP trunking over OpenVPN. The device in question will act as a security firewall to separate the phone network from my LAN. Yes, I could have used the VoIP phone's OpenVPN ability, but I would prefer an additional device with open source firmware that I can fully control unlike the closed phone firware. So the only thing that the device needs to run is an OpenVPN client, a firewall, a DHCP, DNS and a NTP client/server. It technically needs just two Ethernet ports, but I wouldn't mind, if it has a few more (though over 5 is overkill), and I don't want/need any wireless.
Mikrotik routers and similar appliances typically start from 200 to 300 EUR onwards. I'm looking for something cheaper. Preferably something embedded, not an Intel CPU as that's overkill. I already have two PC Engines APU boards with 3 ethernet ports, but I use one as my main gateway, and the other one is a backup in case my gateway dies. Though, PC Engines APU boards are a bit big for my taste. I'd prefer something smaller that I can mount under the desk.
Summary:
- A router device with embedded MPU that can run OpenWRT
- Strong enough to handle OpenVPN and some VoIP traffic
- Must have 2 to 5 RJ45 ports
- No wireless (wired only)
- DC powered
- Not too expensive i.e. up to 100 EUR
- Preferably small form factor
Thanks in advance for any suggestions.
