I have a client asking about a Sonic TZ170 that was proposed by another company. The internal network will have two subnets (LAN/DMZ) with 15~30 devices in the LAN and 4~8 devices in the DMZ. The DMZ will host the email server, web server, Fax Server, and possibly another support server. The LAN will host workstations, SQL Server, Domain Controllers.
Both networks will have to be accessible via IPSec dedicated device to device tunnels and the firewall has to support PPTP inbound to the Firewall as the end point.
In reading on the TZ170, I've not used one, it looks like it's going to be way under-powered for their needs and that the 2040 series would be the minimum we would want to start with.
Any thoughts or issues that I would want to know about a TZ170 for the above?
