VPN connections are encrypted, this adds extra overhead to the connection and an extra place all data must route through.
Once connected to a VPN your speed is determined by the slowest connection between you and your end point (The site you're visiting, or the service you are using)
For example:
If your home / business connection is a 20mb but your VPN is a 1MB connection, then your speed is going to be less then 1mb once you connect through the VPN.

Encrypted traffic is usually a bit slower, however if you feel speeds are far slower then they should be, you will need to contact the vpn service provider and see if any settings in your VPN software can be changed to speed things up.

How to setup VPN on a D-link Router.



Ok to Setup you VPN follow the instructions below. You can configure DI-804HV, DI-808HV, and DI-824VUP+ by web management interface. Type 192.168.0.1 (The LAN IP is 192.168.0.1 by default) in the browser, and then input user name: admin (there is no password by default) to pass authentication of web management interface. Then finish the configurations as showed below on Gateway A and Gateway B. Configurations of Gateway A 􀂾 Model: DI-804HV (DI-808HV, or DI-824VUP+) 􀂾 Firmware version: v1.40 (You can download the latest firmware on D-Link’s website.) 􀂾 WAN IP Address: 14.15.16.17 (Static IP) 􀂾 LAN IP Address: 10.5.6.1 (Subnet Mask: 255.255.255.0) 􀂾 VPN Configurations: 􀂄 Enable VPN function on Gateway A. 􀂄 Tunnel Name: toGatewayB 􀂄 VPN Method: IKE (Main mode) 􀂄 Local Subnet: 10.5.6.0 􀂄 Local Netmask: 255.255.255.0 􀂄 Remote Subnet: 172.23.9.0 􀂄 Remote Netmask: 255.255.255.0 􀂄 Remote Gateway: 22.23.24.25 􀂄 Pre-share Key: hr5xb8416aa9r6 􀂄 IKE Proposal (Please remember to add the correct proposal ID into the list of IKE Proposal Index when you finish inputting the following information.) 􀀹 Proposal Name: toGatewayB 􀀹 DH Group: Group 2 􀀹 Encryption Algorithm: 3DES 􀀹 Authentication Algorithm: SHA1 􀀹 Life Time: 28800 􀀹 Life Time Unit: Second 􀂄 IPSec Proposal (Please remember to add the correct proposal ID into the list of IKE Proposal Index when you finish inputting the following information.) 􀀹 Proposal Name: toGatewayB 􀀹 DH Group: Group 2 􀀹 Encapsulation Protocol: ESP 􀀹 Encryption Algorithm: 3DES 􀀹 Authentication Algorithm: SHA1 􀀹 Life Time: 3600 􀀹 Life Time Unit: Second 4. Verify the VPN connection Before you start to establish VPN connection between Gateway A and Gateway B, please make sure the Internet connection between Gateway A and Gateway B is workable. You can use “Ping Test” tool on Gateway A (or Gateway B), and input the IP address of Gateway B (or Gateway A) to see if there is any response from its peer device. Connect a PC (called PC_A) to the LAN port of Gateway A, and connect another PC (called PC_B) to the LAN port of Gateway B. Start to “Ping” PC_B on PC_A, then Gateway A will start to establish IPSec connection with Gateway B. If you can get “Ping” responses from PC_B on PC_A, then it means the tunnel has been established successfully. You can also check the “VPN Status” page with web management interface to verify the status of VPN connections. Figure 1: VPN status of Gateway A after IPSec connection has been established. Figure 2: VPN status of Gateway B after IPSec connection has been established.
Hope this helps

Purchased a new D-link router, Cannot open my VPN for my work through the router, what is the problem. My VPN wored before my modem was connected to the router, what can I do?


Not all routers will pass all types of VPN successfully. My last D-Link router would pass a PPTP VPN with no problem, but completely choked on any attempt to pass an IPSEC VPN.
Since you never specified what model router you have, it's difficult to diagnose your problem beyond that observation.
Try a different brand or model of router and see if you get better results. Sad to say, I have found that the low-end routers work fine with completely vanilla networks, but they are very prone to annoying surprises like this when you try anything beyond what the average home user would try.

Can't connect to AT&T VPN


as you told me that all the ports are open so in that case you can get in touch with your ISP and ask them to enable IPPASSTHROUGH on your office laptop.

DLink DI-624s - can't get Cisco VPN Client to connect.


The "Virtual Server" setting is designed to give the general public access to a network resrouce (web/ftp/media server) on your internal network. If your the VPN concentrator is external to your network (meaning you'll have to use the internet to connect to it), then you won't need to define a virtual server on the DI-624.

You'll just need to enable the IPSEC and PPTP VPN Passthrough which it sounds like you've already done this. I've run into some ISP's that block VPN connections out of their network. If you have the ability, try to directly connect your laptop into your cable/DSL modem in place of your router and see if you can make a VPN connection, if not contact your ISP, if you can then verify you enabled the VPN passthroughs because your router is blocking them.

GIve it a shot and let us know your results.

Can't connect to AT&T VPN


I'll need to know what router you're using, make and model, for more specific help, but sometimes there is an option for IPSec passthrough. For example, on my Linksys Wireless Router WRT54G, there is a set of buttons under Security/VPN that are entitled IPSec Passthrough, PPTP Passthrough, and L2TP Passthrough. Since I don't know what router you're using, I can't tell you wether or not your router supports such functions or not, but if it does, you need to enable them.

Cisco VPN Client won't connect


You'll want to enable the VPN transparency. In the router's administrative web interface, click the Security Tab, then the VPN Passthrough sub-tab. Cisco VPN's usually use IPSEC, so enable the IPSEC Pass-through and click "Save Settings". If this doesn't work enable the PPTP Pass-through as well and give that a shot.
