Personal Firewall Rules
| Summary | Cisco VPN Client cannot establish VPN connection due to Personal Firewall. |
| Solution |
Typically a Personal Firewall will display a
prompt to permit or deny the Cisco VPN Client when a VPN connection is
initialised, and automatically generate a firewall rule. If your
Personal Firewall does not support this feature, you will have to
configure it manually with the rules specified in the table below. Source Network Source Protocol/ Service Destination Network Destination Protocol/Service >>> Outbound rules (from your PC to the server) >>> Client ESP VPN Servers * ESP Client UDP 500 (isakmp) VPN Servers * UDP 500 (isakmp) Client UDP > 1023 VPN Servers * UDP 500 <<< Inbound rules (from the Server to your PC) <<< VPN Servers * ESP Client ESP VPN Servers * UDP 500 (isakmp) Client UDP 500 (isakmp) VPN Servers * UDP > 1023 Client UDP 500 (isakmp) * UCL VPN Servers - 128.40.255.64/29 (Subnet Mask 255.255.255.248) |
