• Question 11: I still can't get my tunnel to work after attempting to initiate traffic
between the two subnets. What now?
Try the following troubleshooting tips:
• Verify you can ping each of the remote Gateway IP addresses from clients on either side.
Failed pings can indicate general network connection problems.
• Pinging the internal gateway address of the remote subnet should run the ping through
the tunnel as well. Allowing you to test, even if there are no clients on the remote end.
• Question 12: My tunnel works fine when I use the LAN-WAN Access page to
configure my firewall. Now that I use Advanced LAN Access, my VPN stops
working. What am I doing wrong?
VPN requires certain packets to be passed through the firewall. Subnet Access
automatically inserts these rules for you when you do VPN. Advanced Subnet Access
requires these rules to be in effect for each tunnel.
• An 'allow' inbound rule.
• An 'allow' outbound rule.
• For IKE, an 'allow' inbound rule.
