  1. Anyone here have experience with OpenBSD 6.3 as a guest under libvirt? I've spun up a couple instances on my CentOS 7 KVM/libvirt host and I cannot seem to get more than roughly 100Mbps network performance from them. Using the virtio NIC I can sustain transfer rates of roughly 12 MB/sec. I tried switching to the e1000 NIC and performance was worse ( ~8 MB/sec sustained transfer rates with it) even though the virtual NIC indicated it had a 1000baseT full-duplex link. I did not try the rtl8139. Any ideas?
  2. So far so good! I have yet to have media suddenly disappear on me in the middle of a call.
  3. Ooooooh once my office is put back together I'm so contributing to this.
  4. I've been debating on which direction to go with regards to my perimeter firewall on my home network. In talking to systems_glitch in IRC he suggested that I give OpenBSD a go (he probably regrets this as I've been bugging this crap out of him about it). I was a little gun shy about it at first since it would be my first experience with pf, and even OpenBSD itself, but the *NIX nerd in me decided to dive in head first. Although it's only been a couple of days, I am very happy with the setup! I used an old Dell OptiPlex 755 inherited from the ewaste pile at $dayjob. It's got an Intel Core2 Duo E650 2.33 GHz CPU, 8 GB RAM, a 128 GB SSD, gigabit NIC onboard. I happened to have an Intel PRO/1000 quad PCIe NIC in my stash which other than needing a half-height bracket (ordered and en-route from good ol' China) works beautifully. Until the bracket arrives I'll just run it with the cover off. The machine could use a nice does of compressed air, too. Performance wise I am very impressed. I was leary of a box like this being able to handle gigabit throughput between firewall zones, but this box handles it like a champ. CPU usage when doing scp between two hosts on separate zones is maybe 30% peak. I have enabled some additional logging since this testing so I suspect CPU usage will be higher...I plan to test this soon. Right now I'm using the onboard NIC as the "WAN" interface and a single interface on the PRO/1000 card for an inside zone. Eventually I'm going to put all 4 of the PRO/1000 interfaces in a LACP bond and set up multiple zones using VLANs, but that is dependent on another network project of mine that is still in progress. Before this I was using a Ubiquiti EdgeRouter PoE. I can tell you hands down I prefer pf & OpenBSD wayyyy more over EdgeOS/VyOS. If anyone has any tips/tricks on configuring pf security/performance wise, I am all eyes. My config for reference (it's fairly basic right now): https://ghostbin.com/paste/sjfav And, the obligatory pics!
  5. I purchased a Simonics Google Voice bridge (https://simonics.com/gw/) and it works beautifully. I'd like to purchase another so I have a second DID. Does anyone know if they'll allow two SIP trunk registrations from the same host/IP? For $6 I was going to just give it a shot, but they're not taking sign-ups right now. So I figured while I wait I'd ask here. :-D
