The router can be set to forward incoming connections to IP addresses on your network on a per-port basis, and can also set one IP address to be a DMZ host. UPnP can also be enabled to allow programs on your network to open ports as required, but was disabled by default. However, the 7390 does not have support for accounts with multiple IP addresses from your ISP. It can only forward ports from the router's own external IP address, and incoming connections cannot be filtered by source. These missing features are common in business-class routers, so their omission here is notable.
Other features include Dynamic DNS support for both predefined providers and for user defined ones, a built in print server, UPnP streaming of media on attached USB drives, QoS prioritization (which was preconfigured for VoIP traffic), call blocking, site blocking controls which can be configured on a per-computer basis for your network and remote control of the router from inside your network using iPhone and Android apps.
Although its wireless performance is somewhat underwhelming, it's not bad enough to make us any less impressed by this router, although you might want to invest in an additional wireless access point if you want to extend a 2.4GHz network over a wide area that suffers from significant interference. For the small office requiring internet access and phone services in a single device, the Fritz!Box Fon WLAN 7390 is ideal. Simple to use and full of features, it lets you effectively handle almost all your office communications needs with a single compact device.
