IPsec Tunnel

The IPsecTunnel class manages IPsec tunnel objects in Palo Alto Networks' Strata Cloud Manager. It extends from BaseObject and offers methods to create, retrieve, update, list, fetch, and delete IPsec tunnels. IPsec tunnels provide encrypted connectivity between sites and complete the VPN stack alongside the existing IKE Gateway and IPsec Crypto Profile services. Each tunnel requires an auto_key configuration that references one or more IKE gateways and an IPsec crypto profile.

Methods

List IPsec Tunnels

# List all IPsec tunnels in a folder
tunnels = client.ipsec_tunnel.list(
   folder="Texas"
)

# Process results
for tunnel in tunnels:
   print(f"Name: {tunnel.name}")
   print(f"  IKE Gateway(s): {', '.join(gw.name for gw in tunnel.auto_key.ike_gateway)}")
   print(f"  Crypto Profile: {tunnel.auto_key.ipsec_crypto_profile}")
   print(f"  Anti-Replay: {tunnel.anti_replay}")
   if tunnel.tunnel_monitor:
      print(f"  Tunnel Monitor: {tunnel.tunnel_monitor.destination_ip}")

# List with crypto profile filter
filtered_tunnels = client.ipsec_tunnel.list(
   folder="Texas",
   ipsec_crypto_profile=["aes256-sha256", "suite-b-gcm-256"]
)

for tunnel in filtered_tunnels:
   print(f"Filtered tunnel: {tunnel.name} ({tunnel.auto_key.ipsec_crypto_profile})")

Filtering Responses

The list() method supports additional parameters to refine your query results even further. Alongside basic filters, you can leverage the exact_match, exclude_folders, exclude_snippets, and exclude_devices parameters to control which objects are included or excluded after the initial API response is fetched.

Parameters:

• exact_match (bool): When True, only objects defined exactly in the specified container (folder, snippet, or device) are returned. Inherited or propagated objects are filtered out.
• exclude_folders (List[str]): Provide a list of folder names that you do not want included in the results.
• exclude_snippets (List[str]): Provide a list of snippet values to exclude from the results.
• exclude_devices (List[str]): Provide a list of device values to exclude from the results.

Examples:

# Only return tunnels defined exactly in 'Texas'
exact_tunnels = client.ipsec_tunnel.list(
   folder='Texas',
   exact_match=True
)

for tunnel in exact_tunnels:
   print(f"Exact match: {tunnel.name} in {tunnel.folder}")

# Exclude all tunnels from the 'All' folder
no_all_tunnels = client.ipsec_tunnel.list(
   folder='Texas',
   exclude_folders=['All']
)

for tunnel in no_all_tunnels:
   assert tunnel.folder != 'All'
   print(f"Filtered out 'All': {tunnel.name}")

Controlling Pagination with max_limit

The SDK supports pagination through the max_limit parameter, which defines how many objects are retrieved per API call. By default, max_limit is set to 2500. The API itself imposes a maximum allowed value of 5000. If you set max_limit higher than 5000, it will be capped to the API's maximum. The list() method will continue to iterate through all objects until all results have been retrieved. Adjusting max_limit can help manage retrieval performance and memory usage when working with large datasets.

Example:

from scm.client import Scm

# Initialize client
client = Scm(
   client_id="your_client_id",
   client_secret="your_client_secret",
   tsg_id="your_tsg_id"
)

# Configure max_limit using the property setter
client.ipsec_tunnel.max_limit = 4000

# List all tunnels - auto-paginates through results
all_tunnels = client.ipsec_tunnel.list(folder='Texas')

Fetch an IPsec Tunnel

# Fetch by name and folder
tunnel = client.ipsec_tunnel.fetch(
   name="site-a-to-site-b",
   folder="Texas"
)
print(f"Found tunnel: {tunnel.name}")
print(f"  IKE Gateway: {tunnel.auto_key.ike_gateway[0].name}")
print(f"  Crypto Profile: {tunnel.auto_key.ipsec_crypto_profile}")

# Get by ID
tunnel_by_id = client.ipsec_tunnel.get(tunnel.id)
print(f"Retrieved tunnel: {tunnel_by_id.name}")
