Zy WALL&trade 2 plus is a powerful firewall with security support for tap-proof connections. The integrated processor enables web-based content filtering directly in the firewall. This allows, among other things, undesired URLs & key words to be blocked for the entire network. The enhanced VPN functions of Zy WALL&trade 2 plus enable an AES encryption rate of 24 MBit/s & 5 VPN connections. Failover & Failback technology redirects WAN port traffic to backup ISDN or analogue modems in the event of a WAN port connection failure. When WAN port connectivity is reestablished traffic is automatically redirected again.
