Configuring Via the WAN Router Setup Dialog Box
WAN Router Setup Dialog Box Overview
The WAN Router Setup dialog box has two major sections:
- WAN Router: This section configures local settings and contains three subsections: Router Use,Data To Route, and Global Connections Actions.
- Neighbor Configuration: This section configures the connection information that the WAN Router needs to connect to its peer (i.e., neighbor) on the other network segment. This information includes the neighbor's internal and external IP Addresses as well as the type of connection (active or passive).
You use the WAN Router section to configure local settings (i.e., the machine on which you are currently working). Once you configure the WAN Router section and click OK, Guardian writes your settings to the ttmrd.cfg file.
In addition to its three subsections, the WAN Router section contains the Local IP Address component. When configuring the TTM WAN Router Setup dialog box, on the Local IP Address list, click the IP address of the machine that TTM uses for local network communications (i.e., the host machine's LAN IP Address).
The Router Use subsection contains the following component:
Multicast Domain box: The domain name on which the neighbor is located. This domain needs to match for all routers on a network segment. The field is empty by default.
Warning: When you setup a network WAN Router, you must enter the exact same value, character for character, in the Multicast Domain box as all other network WAN Routers on the same network segment. Additionally, this multicast domain must differ from the multicast domain you use for the remote network segment to which you connect.
Data To Route
The Data To Route subsection contains the following components:
- Production: Select this option if the WAN Router must send production information between network segments. By default, this option is selected.
- Simulation: Select this option if the WAN Router must send simulation information between network segments. By default, this option is not selected.
These options are not mutually exclusive. Select both if the WAN Router must send production and simulation data between network segments.
Global Connection Actions
The Global Connection Actions subsection contains the following components. By default, neither option is selected:
- Prices TCP No Delay: Select this option to set the WAN Router to nagle its price feed. Nagling better conserves bandwidth between your network segments by consolidating price updates. Select this option if you do not want the WAN Router to nagle its price feed. While selecting this option speeds up price-feed performance, it consumes additional bandwidth. By default, this setting is not selected.
Note: This setting affects the sending of price data only and does not need to be identical on each side of the network: one WAN Router can be set to nagle data, while the other is set to send and receive data normally. If you want to also nagle non-price data, you must manually configure the ttmrd.cfg file. For further information, refer to TT Trading Systems - Network Administration Manual document.
- Accept any: Select this option if you want the network WAN Router to accept all incoming TTM router daemon connections. If this option is not selected, the WAN Router accepts connections only from those WAN Routers in the Neighbors list (refer to the section below called Neighbor Configuration). By default, the Accept any option is not selected.
These options are not mutually exclusive. Thus, if the WAN Router must be passive and allow any network WAN Router to connect, select both options.
You set the connection information for remote network WAN Routers in the Neighbor Configuration section. The local WAN Router (i.e., the machine on which you are currently working) uses this information to:
- Connect to the remote network WAN Routers
- Allow the remote network WAN Routers to connect to it
Refer to the topic called Verifying WAN Routing Failover for information on how the TTM Router daemon functions in a network segment.
Note: Network WAN Routers on the network segment to which you connect are referred to as Neighbors.
The Neighbor Configuration section contains the following components:
|Neighbors||This list displays all of the Neighbors that you have set up.|
Enter the domain name on which the Neighbor is located.
Note: All Neighbors that reside on the same remote network segment must use the same Multicast Domain. This Multicast Domain must be different from the local network segment's multicast domain (i.e., the multicast domain on which your machine is currently located).
|External IP||Enter the visible IP address of the Neighbor. Thus, if a Network Address Translation (or NAT) firewall separates the networks, you must enter the Neighbor's outer IP Address.|
|Internal IP same as External IP||By default this option is selected and means that the Neighbor is not NATed across network segments. If the Neighbor is NATed between the network segments, clear this option.|
|Internal IP||This box becomes available only if you clear the Internal IP same as external IP option which means that the neighboring WAN Router is NATed across network segments. Enter the Inner IP Address (LAN IP Address) of the Neighbor.|
Select this option if you do not want the WAN Router to actively connect to this Neighbor. Instead, the WAN Router waits for the router daemon on the Neighbor to connect to it. If this option is not selected, the WAN Router actively connects to this neighboring WAN Router.
Certain scenarios might require you to make a Neighbor for Passive Connect:
|Compression||Select this option to configure compression between two WAN Routers.|
|Add||Click Add after you enter all relevant information for the neighboring WAN Router. This adds the WAN Router to the Neighbors list.|
|Delete||Click Delete to remove a WAN Router from the Neighbors list. You must select a WAN Router in the Neighbors list before you click Delete.|
|Change||Click Change to edit the connectivity information for a neighboring WAN Router. You must select a WAN Router in the Neighbors list before you click Change.|
|Clear||Click Clear to reset the Neighbor Configuration section. All boxes and options revert to their default settings.|
