Why can’t I share my local resources on the PC where CityNET VPN client is loaded when I am connected or disconnected from CityNET VPN?

Symptom is you may not be able to share printers and access network drives from another computer on your LAN to the PC where CityNET VPN client is loaded.

The CityNET VPN client includes a Desktop firewall software whose policy is explained in Desktop Firewall Software . This policy does not allow any inbound access whether you are connected or disconnected to the VPN. This is to protect your computer from intruders. If you like, you may completely disable the VPN client by stopping the client by right clicking on the System Tray “Secure Client” icon.

Why is my Internet access is slow when I am access Internet while I am connected to CityNET VPN?

When you are connected to CityNET VPN, you will be assigned an DNS server by the VPN and DNS name resolutions for both CityNET and Internet names will be resolved by the CityNET DNS servers. This may sometimes be slower than resolving using your ISP. We recommend DISCONNECTING from CityNET VPN when you do not have a need to use it, during which time you will start using your ISPs DNS server.

Can I have multiple VPN clients loaded on my computer like Cisco VPN and Nortel VPN in addition to CityNET VPN client?

CityNET VPN client is based on Checkpoint NG AI Secure Client software. As per Checkpoint, the Secure Client can run with ANY existing VPN solution, since Secure Client binds to a port different from 500 (used for IKE). Some basic tests with Nortel and Cisco VPN did not show any problem with our Clients.

What ports do I have to open if there are firewalls in my path to Internet?

CityNET VPN needs UDP/500, UDP/2746 between the VPN client PC and the CityNET VPN servers.

CityNET VPN client takes care of most issues with NAT and firewall filtering for home users by tunneling IPSec over UDP packets on port UDP/2746. However, there may be situations where you have to enable IPSec passthru, port forwarding, creation of DMZ host on the home firewall devices. Refer to the documentation of your device to find out how to do this.

Are there any known issues for AOL users?

If AOLnet connections cannot be used, please use MtuAdjust.exe (located in the
