We have acquired a new client that has 98 remote endpoints. At each site
there is a need for 4 ip telephones and two vpn tunnels back to
two separate datacenters. (1 voice, 1 citrix farm). The sites don't talk
to each other, just to the two data centers.
Does anyone have a suggestion for a single piece of hardware that would
support 8 or less Ethernet interfaces and the two vpn tunnels ?
A PCengines Alix 2D3 with pfSense/m0n0wall and OpenVPN UDP tunnels to the datacenter combined with a Power over Ethernet switch would seem a likely combination. A HP Procurve 8 Port gigabit desktop switch with PoE comes to mind. Not too expensive, fanless, quiet, reliable does VLANS.
That way you can power the router and phones from the same (smallish) UPS. Say a 700VA APC.
IFRC, the 19xx and 18xx are slower than the new 89x series. We are transitioning away from 18xx because of limitations on the platform that the 89x doesn't have. When the 18xx came out a few years ago they were amazing, the new 89x are even better.
