5.5.5.4 Internal SRV Table
The Internal SRV table is used for resolving host names to DNS A-Records. Three different
A-Records can be assigned to a hostname. Each A-Record contains the host name,
priority, weight, and port.
The ini file parameter SRV2IP is also used to configure the Internal SRV table and has the
following format: <Internal Domain Name>, <Transport Type>, <DNS Name 1>, <Priority
1>, <Weight 1>, <Port 1>, <DNS Name 2>, <Priority 2>, <Weight 2>, <Port 2>, <DNS
Name 3>, <Priority 3>, <Weight 3>, <Port 3>. This parameter can appear up to 10 times.
Note: If the Internal SRV table is configured, the gateway first tries to resolve a
domain name using this table. If the domain name isn’t found, the gateway
performs an SRV resolution using an external DNS server.
¾ To configure the Internal SRV table, take these 9 steps:
1. Open the ‘Internal SRV Table’ screen (Protocol Management menu > Routing
Tables submenu > Internal SRV Table option); the ‘Internal DNS Table’ screen is
displayed.

2. In the ‘Domain Name’ field, enter the hostname to be translated. You can enter a
string up to 31 characters long.
3. From the 'Transport Type' drop-down list, select a transport type.
4. In the ‘DNS Name 1' field, enter the first DNS A-Record to which the hostname is
translated.
5. In the ‘Priority’, ‘Weight’ and ‘Port’ fields, enter the relevant values
6. Repeat steps 4 to 5, for the second and third DNS names, if required.
7. Repeat steps 2 to 6, for each Internal SRV Table entry.
8. Click the Submit button to save your changes.
9. To save the changes so they are available after a hardware reset or power fail, refer to
Section 5.9.2 on page 124.
