Apsara stack Firewall is a comprehensive product series that covers the business needs of small to large enterprises. Taking the flying tower firewall 310B as an example, it is a product for medium-sized enterprises. It integrates routing (supporting RIP, OSPF, BGP and Multicast), unified Threat Management (UTM), VPN, WAN optimization, Gateway proxy, and wireless control. The Apsara stack firewall supports ipsec vpn and ssl vpn, which have unique configuration and monitoring features. This artic

However, tunnel technology cannot directly communicate with IPv4 hosts and IPv6 hosts.IPv6-over-IPv4 GRE Tunneling TechnologyUsing the standard GRE tunneling technology, IPv6 data packets can be carried over IPv4 GRE tunnels. The GRE tunnel is a connection between two points. Each connection is a separate tunnel. The GRE tunnel uses IPv6 as the passenger protocol and GRE as the bearer protocol
