Configure Network for Remote Access by a Public IP Address
To ensure that remote Linkus clients and other SIP devices can communicate with Yeastar P-Series Software Edition normally, you need to configure Public IP and Ports on the PBX. This topic provides a configuration example based on the network scenario that a static public IP address is supplied by the Internet Service Provider (ISP).
Background information
This topic assumes that your network environment is as follows:
- Public IP address: 220.169.10.2
- Local network:
- 192.168.6.0/24
- 192.168.5.0/24
Prerequisites
- If SIP ALG option is provided in your router, disable it.
- You have configured NAT settings and forwarded the following ports to allow
remote access of Linkus clients and other SIP devices. To check the relevant
internal ports of your PBX, see Manage Service Ports of the PBX.
In this scenario, forward the following ports:
Service Internal Port External Port SIP registration UDP 5060 (default) UDP 8092 RTP UDP 10000-12000 (default) UDP 10000-12000 Web server TCP 8088 (default) TCP 9099 Linkus server TCP&UDP 8111 (default) TCP&UDP 6090
Procedure
Based on the scenario, configure the Public IP and Ports on PBX as follows.
- Log in to PBX web portal, go to .
- In Public IP (NAT) section, complete the following configurations:
- Public IP (NAT): Turn on this
option.Note: If a security notice pop-up appears, you can set up allowed country/region IP access protection to better secure remote access.
- NAT Type: Select Public IP Address .
- Public IP Address: Enter 220.169.10.2.
- Local Network Identification: Add all
your local network. This setting will allow all your local
devices to communicate with the PBX by the local IP address
instead of passing through the router.
In this scenario, add two local network: 192.168.5.0/255.255.255.0 and 192.168.6.0/255.255.255.0.
- NAT Mode: Select a SIP NAT mode. In this
scenario, select Yes.
- Yes: Use NAT and ignore the address information in the SIP/SDP headers and reply to the sender's IP address and port.
- No: Use NAT mode only according to RFC3581.
- Never: Never attempt NAT mode or RFC3581 support.
- Route: Use NAT but do not include rport in headers.
- Public IP (NAT): Turn on this
option.
- In the Public Ports section, enter the external ports
that you have forwarded on your router.
- External SIP UDP Port: Enter 8092.
- External SIP TCP Port: Leave it blank because SIP TCP protocol is not used in this scenario.
- External SIP TLS Port: Leave it blank because SIP TLS protocol is not used in this scenario.
- External Linkus Port: Enter 6090.
- External Web Server Port: Enter 9099.
- External LDAP Port: Leave it blank because LDAP protocol is not used in this scenario.
- Click Save.
Result
- Users can remotely access the PBX web portal and log in to Linkus clients via the public IP address.
- Remote devices based on SIP protocol can register to the PBX via the public IP address.
- PBX will generate login links and QR codes for Linkus remote access based on
the information provided on the Public IP and Ports page.Note: If you have configured network for remote access by a Yeastar FQDN, the login links and QR codes are generated based on the FQDN.
