# Prepare to initiate log push connection **Connect from the log pusher to the vMontior Platform system.** | **Source** | **Destination** | **Port** | | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | | Log pusher IP | Subnet range: 116.118.93.130/28, i.e. 116.118.93.128 -> 116.118.93.143 | 10092 TCP | | Log pusher IP | Domain: [hcm01-loghub01.vngcloud.vn ](http://hcm01-loghub01.vngcloud.vn/)[hcm02-loghub01.vngcloud.vn ](http://hcm02-loghub01.vngcloud.vn/)[hcm03-loghub01.vngcloud.vn](http://hcm03-loghub01.vngcloud.vn/) | 10092 TCP | * The above connection needs to be open during the agent pushing logs If the machines need to collect logs, some machines cannot open a direct connection. Refer to using the [collector](https://opentelemetry.io/docs/collector/) model to push through an intermediate host. *** **Domain resolution** Because the transmission channel data is **secured** by SSL encryption standard. If the log pusher is capable of querying public DNS, there is no problem. However, if not (which may occur in an on-premise environment), you need to add domain resolution according to the following table: 
# IP---------------| Domain
