Common Troubleshooting Steps

• Verify basic network reachability: ping the gateway IP.
• Check gateway logs for incoming attempts and reasons for failure.
• Ensure phase 1/phase 2 parameters match exactly (encryption, hash, DH group, lifetimes).
• If behind NAT, enable NAT-T and ensure UDP 4500 and 500 are allowed through firewalls.
• If you see "NO_PROPOSAL_CHOSEN", mismatch in phase 2 proposals—adjust algorithms.
• For authentication failures, confirm PSK or certificates on both sides.
• Temporarily increase logging verbosity in Access Manager to capture detailed negotiation errors.
• Windows firewall: allow Shrew Soft VPN client executable and IPsec services.
• If Windows 11 blocks drivers, allow unsigned driver installation if driver signing is the issue (only if you trust source).
