Hi @sadhna
- Verify Firewall Configuration: Even though the network team has allowed port 161 in the firewall, double-check the configuration to ensure there are no issues. Sometimes, there could be misconfigurations or other rules affecting the traffic.
- Check Connectivity: Ensure that there is proper connectivity between the discovery probe and the SSL VPN devices. You can use tools like ping or traceroute to verify connectivity. Sometimes, the issue might not be with the firewall but with network routing.
- Firewall Logs: Check the firewall logs to see if any traffic is being blocked or if there are any errors related to port 161. This can provide valuable insights into whether the traffic is reaching the SSL VPN devices or not.
- SSL VPN Configuration: Review the SSL VPN device configuration to ensure that it is configured to respond to discovery requests. Sometimes, devices might have settings that restrict or block discovery attempts.
- Network Device Configuration: Ensure that the SSL VPN devices are configured to allow SNMP traffic on port 161. Check if SNMP is enabled and configured correctly on these devices.
- Alternative Discovery Methods: If SNMP discovery is not working, consider using alternative discovery methods such as SSH or WMI depending on the capabilities of the SSL VPN devices. ServiceNow Discovery supports multiple discovery protocols, so exploring alternatives might help in discovering these devices.
