Hi,
i want to configuring the 2 wan links on the IAM Sangfor. does anybody guide me or share any documentayion how to configure failover between the two Wan Links

Configuring WAN Failover on Sangfor IAM Firewall

There are two main approaches to configure failover between two WAN links on a Sangfor IAM firewall:

1. Link Load Balancing with Failover:

This method uses Sangfor's built-in Link Load Balancing feature with failover capabilities. Here's a general outline of the steps involved:

    Enable Link State Detection:
        Go to Network Interface > WAN Link (choose your specific WAN interface).
        Click on Link State Detection Settings at the bottom.
        Enable Link State Detection and choose the appropriate method (e.g., PING) to monitor your WAN connection health.
        Set the Destination IP for each WAN link (usually the ISP gateway IP).

    Configure Link Load Balancing Policy:
        Go to Bandwidth Management > Link Load Balancing.
        Click Enable link load balancing policy. Confirm the prompt.
        Ensure the line state detection shows "Normal" for both WAN links.
        Under Default Link Load Balancing Policy, choose a pre-configured policy or create a new one.

    Configure Failover Policy (within Link Load Balancing Policy):
        When creating a new policy, you can define failover behavior.
        Specify conditions for failover (e.g., link down, packet loss exceeding a threshold).
        Choose the backup WAN link that takes over traffic when the primary link fails.

2. Policy-Based Routing with Failover:

This approach uses policy-based routing with failover rules. Here's a simplified overview:

    Define Network Objects:
        Go to Network Objects and create objects representing your WAN interfaces and internal network segments.

    Configure Routing Rules:
        Go to Route > Policy Route.
        Create routing rules that prioritize your primary WAN link for outgoing traffic.
        Include failover rules that divert traffic to the secondary WAN link if the primary link fails. You can base these rules on link status or other criteria.

Hi,

There are several ways to configure 2 WAN links on Sangfor IAM.

1. Link State detection
   - login to Sangfor IAM web interface and go to Network > Interface > WAN Link
   - Click the link stte detection settings for each WAN link (usually at the bottom of the page), Enable the link state detection.
   - You may try to monitor the health using PING
   - configure and set the destination IP address of the link using the IP Gateway of the ISP and click Commit to save the changes.

2. Failover policy
   - go to Bandwidth Management > Link Load Balancing and click "Enable link load balancing policy".
   - confirm that the line state detection you configured will show "Normal" status for both links

HiHi,

You can configure Link Load Balancing, Enable Link State Detection, and set network failover policies.

Hi, setting up failover between two WAN links on Sangfor IAM requires a series of steps. Here’s the steps:

Activate Link State Detection: This feature is utilized to keep track of your WAN links’ status. The Destination IP can be set to your ISP’s gateway IP.
Set Up Policy Based Routing: Once link state detection is enabled, navigate to Network > Routing > Policy Based Routing and incorporate a Link Load Balancing Route.
Incorporate Network Objects: Include the interface of your WAN links for the failover process.
Establish Zones and Network Objects: These are employed to aggregate a group of IP addresses.
Implement NAT: Apply Network Address Translation (NAT) from the LAN to the WAN zones.

To configure failover between two WAN links on the IAM Sangfor, you typically need to access the Sangfor IAM management interface and navigate to the network or WAN configuration section. From there, you can set up policies or rules to define the failover behavior, specifying criteria such as link availability, response time, or traffic load. Ensure that both WAN links are properly configured and connected to the IAM appliance.

you can try Sangfor managment console for IAM and point to network settings/config section.
