Configuring PPTP (VPDN) Server On A Cisco Router

Connecting to the PPTP VPN Server

How to setup site-to-site PPTP VPN on TP-Link Router
Get started today Stand Out as the employee with proven skills. Could a port etc. My question is, am I required to manually add an entry to this table which directly connects both networks together? While it couldn't do any harm to keep these additional ports open apart from posing a security risk , I'm going to attempt to disable each of the additional ports and leave TCP on - then try a dial-up VPN connection again. The remote user will need the above username and password to successfully connect to the VPN. Ask your question anytime, anywhere, with no hassle. But I do not see any vpdn calling debug which is enabled!

Router - Router PPTP VPN troubles

R1 configure terminal R1 config vpdn enable R1 config vpdn-group 1 R1 config-vpdn accept-dialin R1 config-vpdn-acc-in protocol pptp R1 config-vpdn-acc-in virtual-template 1 R1 config-vpdn-acc-in exit.

The above configuration enables the router to accept incoming PPTP connections and specifies the virtual interface to which the PPTP tunnel is configured. Next up, we need to bind the virtual interface to a real interface. This effectively binds the PPTP connections to the real interface. The ' ppp encrypt ' command specifies the encryption to be used - in our case, that's bit.

This can be set to 'auto' for maximum compatibility. The authentication is set to ms-chap and ms-chap v2 so that we can offer the best possible authentication method for this case. All VPDN clients will either obtain an IP address that is part of the existing internal network as in our example , or they will be assigned an IP address that is totally different from the internal network scheme e.

If on the other hand you wish to provide VPDN clients with a totally different IP address from that of your internal network, then you must configure the Virtual-Template interface with an IP address belonging to that network e. From the configuration and diagram provided so far, you can see that we'll be assigning the VPDN clients an IP address range that's part of the existing internal network:.

Last step is to create the user accounts our VPDN clients will require to authenticate to the router and access internal resources. This is a fairly simple task as you only need to add a username, followed by the password:. The remote user will need the above username and password to successfully connect to the VPN.

This method has worked when dialing up to the domain from the 2nd Network using a 56k Modem, I was able to successfully establish a VPN connection after connecting to the Internet through my ISP. There is no such client installed on the 2nd Network so far it has been unneccesary to.

So far there has been no activity of course, there was when the dial-up connection was established. Could it be that I need to configure the routing tables of each ADSL router to bridge both connections? If so, is there a way which I can do this without the need for static IP addresses? I would greatly appreciate some advice on how to set up routing table entries, I have not been able to fully understand the purpose of the Destination IP, Gateway, Subnet in their respective contexts.

While I am familiar with networking in general, routing tables are currently beyond my comprehension. My thanks in advance for any insight you may have.

There is no routing that needs to happen on the router itself. Some information that may help: U could just check this out; http: Something you might be able to try to find out if its actually a routing problem is to do a tracert to the device wich should authenticate you.

It might be that the network experiences a routing loop. You will notiche this if in the tracert you get something like this: As you can see the packet keeps going back in a loop.

The concept of routing tables: If a packet is trying to reach a certain IP address it should be sent to the following address the gateway Subnet: Someone from the LAN Your network has an internet connection with a certain ISP. That ISP gives you acces to the internet by mean of a gateway The routing table should have the following entry: That gateway will route the packets so they will reach the external mailserver.

The routing table actually says: I hope this explanation will help you to understand routing tables a bit better. I'm not sure how correct that is as 'lrmoore' has explained that it is a local protocal that is initiated in response to a TCP request. While it couldn't do any harm to keep these additional ports open apart from posing a security risk , I'm going to attempt to disable each of the additional ports and leave TCP on - then try a dial-up VPN connection again.

Thanks StevieWonder for your explanation of Routing Tables - much appreciated. My question is, am I required to manually add an entry to this table which directly connects both networks together? Or do I just need to keep the existing route which connects the network to the Internet? I realise that this is all that is required for a modem connection - is there anything additional I need to do in order for a Router to Router connection to work? Keep in mind everyone that I can successfully initiate the VPN connection using a modem.

So there is obviously something wrong at the NetGear Router's end. A bit more information about the NetGear router I have tried this but I have still had no luck. Is further exploration here needed? Also, do I need to mess with enabling ports with the Netgear? Is this a problem? I will a local Tracert on the network in the mean time to check for a routing problem.

Configuring a PPTP client on TP-Link Router Step 1: Access Router B’s management page, go to L2TP/PPTP Tunnel, look for protocol, select PPTP ; the Mode should be Client.
