About forwarding non-TCP traffic through an iSession over IPsec tunnel

When you configure WAN Optimization Manager™ (WOM®) using the Quick Start screen, you can specify IPsec encapsulation for outbound iSession™ traffic. The BIG-IP® WOM system automatically creates the necessary virtual servers for optimizing TCP traffic. If you also want to send secured and encrypted non-TCP traffic, you can create a forwarding virtual server and associate an iSession profile to send non-TCP traffic through the iSession over IPsec tunnel.

Creating a virtual server for non-TCP iSession traffic

If you are using IPsec to encrypt iSession™ traffic, you can create a forwarding virtual server to also send non-TCP traffic through the IPsec tunnel. Creating the virtual server avoids the need for any special routing for non-TCP traffic, such as UDP and ICMP.
  1. On the main tab, click Local Traffic > Virtual Servers.
  2. Click the Create button.
  3. Type a unique name for the virtual server, such as non_tcp_traffic.
  4. For the Type setting, select Forwarding (IP) from the list.
  5. For the Destination setting:
    1. For Type, select Network.
    2. In the Address field, type the IP address 0.0.0.0.
    3. In the Mask field, type the netmask 0.0.0.0.
  6. In the Configuration area of the screen, from the Protocol list, select *All Protocols.
  7. From the VLAN Traffic and Tunnel Traffic list, select All VLANs and Tunnels.
  8. In the WAN Optimization area of the screen, from the iSession list, select an iSession profile.
  9. Click Finished.
The completed screen looks similar to the following example.
