The Ubiquiti edgemax routers are also pretty nice and cheap, they have a good GUI. I remember also someone here posting how he runs openbsd in the edgemax routers.
If you're in the Bay, Streakwave (authorized Ubiquiti dealer) is right in San Jose: https://www.streakwave.com/mobile/searchresult.asp?Tp=
(WASD keyboards, makers of the CODE keyboard, are also in the Bay Area and do local pickup as a delivery option!)
I've been quite pleased with the uptime and performance of my little $100 million-packet-per-second router. I used to be a big believer in pfsense, but the ERLite got me to retire that old thing.
It doesn't support "vmware tools" as such, but does support the virtual interfaces for network, disk, ballooning etc...
It sounds like that was previously the case, but the complaints above appear to be pfsense in a VM and debian in a different VM. Why wouldn't that scenario be supported?
I had a backup server running Ubuntu with ZFS which was always on anyways so I just had to install pfSense on OS disk and it imported the ZFS disks right away. So for a long time it was both my backup server and the router/firewall.
But lately with all the upgrades (including 2.3 betas and RCs I ran) SAMBA throughput was reduced significantly - not entirely sure if it were the drivers, ZFS or something else. And I realized maybe it is not such a great practice to make your router/firewall double up as a backup server. So I virtualized the box using ESXi and ran pfSense and Debian in two VMs on it.
The box being weak and running virtualized along side another backup server VM exposed the performance issues with pfSense - I had given a single CPU and 512Mb to it and with the GUI and other process overheads - DNS cache, pingers etc. meant that I had noticeable slowdowns when both VMs were active.
I am giving VyOS a try - it's a debian based router distro and purely command line based but resource utilization wise it seems to be doing fine with 512Mb and single CPU.
Anyone having a low power dedicated box for pfSense should just use pfSense though - the UI is way too good in 2.3 release and stuff just works - IPV6, Tunneling, VPN are very easy to configure along with a bunch of other things limited only by the box you're running it on.
