The "Error_Ipsec_Transport_Filter_Exists" means that there's already a filter with the same settings in the system, which stops new ones from being added.
This can happen if someone makes a mistake, multiple people change settings at the same time, or if a script doesn't check for existing filters. When this error occurs, it can cause connection problems and make the network less secure.
To fix it, check the current filters and remove any duplicates. To prevent this error, always double-check settings and coordinate changes with others. Understanding this error helps keep networks safe and running smoothly.
Error meaning:
The "Error_Ipsec_Transport_Filter_Exists" message means you tried to create a security filter that is already in use.
This prevents new filters from being added, so you need to check and change the existing ones to fix the problem.
Causes:
Potential reasons for the "Error_Ipsec_Transport_Filter_Exists" message:
- A filter with the same settings already exists in the system.
- An administrator accidentally tries to add a filter that is already there.
- Multiple administrators are working on filters at the same time without talking to each other.
- Automated scripts are running that don't check for existing filters before trying to create new ones.
Symptoms:
When users see the "Error_Ipsec_Transport_Filter_Exists" message, they might notice these problems:
- They can't connect securely to other computers or networks.
- The network is slow, with delays or lag.

- There might be duplicate filters causing confusion.
- Users may see error messages or alerts about problems in the IPsec settings.
These issues usually mean that the transport filters in the network are set up incorrectly or are overlapping.
Solutions:
Step 1: Access the IPsec settings on your system.
Step 2: Look for any IPsec policies that are already set up.
Step 3: Check for transport mode filters that might be causing conflicts.
Step 4: Use the command line or management console to see a list of current filters.
Step 5: If you find duplicate filters, remove or change them so each filter is unique.
