Change standard ports¶

The ports listed above are standard ports that are configured for a standard versiondog server. These ports can be changed.

To change any port number, proceed as follows:

Stop the VDog MasterService.
In your vdServerArchive folder, open the \VD$A\Configuration\csc.ini file. Each process that listens to a port has its own section. Change the key 4852 in the corresponding section to the new port number.

For example, if you want to change the port of the VDogAPI process to port 64024, the section in the INI file should look like this:
```
[VDogApi.exe]
4850=1
4852=64024
4851=localhost
```
Change your firewall configuration to allow communication through the new port. Contact your local system administrator if necessary.
Restart the VDog MasterService.
