how could i know my Router supports for VPN server.

By sendto_selah ·
really i am not familiar with VPN server, i mean this is my first time but i have some information through reading.
first, let me give you information about the Router. " office connect Adsl wireless 11g Firewall Router" and i have enabled the IP sec NAT -T pass-through. and added ports like PPTP,L2TP AND isakmp, so, from what i mentioned here, do you think that this Router is ready for VPN?

Could you please post the model number? Also 3Com has an excellent knowledge base if you would rather go that route.

VPN PassThru

I am not personally familiar with that particular model, but according to the data sheet it only will configure as a VPN passthru. There is nothing mentioned about the ability to act as a VPN server.

Hi, Sir how are you doing?

if this Router doesn't support to ocnfigure VPN, what is the use of protocols like PPTP,L2TP...and also the IP sec pass-thru, NAT...I mean i can't configure my computer as a VPN SERVER? you said " only will configure as a VPN PASSTHRU" can you explain Sir, what does it mean by VPN passthru?

thank you very much

The fact that the router has the ability to use those protocols does not always mean it can act as a VPN server. It does usually mean that it can act as a VPN client device. The following is from some of my notes:

"A SOHO network device that supports VPN will probably support either IPsec, PPTP, L2TP or SSL VPN technologies. This means that the device actually has an implementation of the protocol running on it and can be used to connect to a central server or VPN gateway; therefore, a VPN client would not be required

On the other hand, a SOHO network device that supports VPN pass-thru simply means that it can support "passing through" packets that originate from VPN clients (typically on laptops or PC's) out through a VPN server on the Internet. A special feature like this is needed because: 1) these SOHO devices are involved with NAT and PAT, 2) VPN protocols like IPsec (the data path is called ESP) doesn't have a specific port number for the device to multiplex the port address translation back to your laptop or PC 3) that's why this feature enables some special processing of packets that are IPsec ESP data packets and allows the device to keep a table of active connected VPN tunnels."
