Description |
Protocol number |
|---|---|---|
| ESP used for IPsec VPN | IPSec VPN tunneling | 50 |
| IP-in-IP | IPv4 IPIP tunneling (also called IP in IP tunneling) | 4 |
| L2TP | Layer Two Tunneling Protocol | 115 |
| CAPWAP | Communication between wireless access points and wired LANs or between different wireless access points | N/A |
| VXLAN | VXLAN and VXLAN over IPsec. Provides secure communication between data centers over public networks. | N/A |
| GRE | Generic Routing Encapsulation. (Offloading GRE over a loopback interface is not supported and offloaded traffic is blocked. In the firewall policy, disable auto-asic-offload to allow traffic to flow.) |

| GTP | GPRS Tunneling protocol | N/A |
| IPv6 encapsulation | Tunnel to send IPv6 traffic over an IPv4 network. | 41 |
