Recently, I purchased a WatchGuard XTM515 Firewall for our company usage. Its price is lower than CISCO and Juniper, but higher than Zyxel and Huawei. So far, WatchGuard is very stable and easy to use. I configured it as the following screen dump for your reference. As a conclusion, I will recommend WatchGuard XTM515 Firewall you.
My Network Port Connection:
- Port # 0 for management console
- Port # 1 for internal network LAN connection
- Port # 5 & 6 for external broadband WAN connection
