XP VPN trouble.

[Guest_imported]

I am attempting to connect 2 LAN's via vpn pptp. Both LAN's are configured in about the same way. Both are made of about 3-4 clients in a workgroup environment. They both have the same workgroup name also (not sure if that matters). Each has a machine connected to a Verizon DSL router and share the net connection with the other machines. The LAN's both work fine individually. The DSL machine that will be accepting the pptp traffic has 2 nic's installed. One connects to the DSL router, and the other to the hub for local traffic. The host is running winodws XP. I have an incoming connections icon created on the host. On the client LAN I am able to connect using a VPN pptp connection without trouble. The host verifies my credentials and a connection icon appears in the lower right of the screen. I am able to ping the hosts machine, but that is where the connection ends. I cannot ping an clients on the HOST lan, nor can I see them in 'my network places'. I have been searching for this answer of 2 weeks now. If someone could even point me in the right direction I would be very greatfull.

nat maybe?

Your machine that is connecting sounds like it is not getting an IP for the network. Check an IPCONFIG while connected. The server has to be configured with a range of IPs to hand out to remote clients, this may have been overlooked.. Matt Wray

When connected I get an Ip of 169.254.254.156. I was able to see the host pc of remote network one time. It was when I bound the pptp server to 192.168.0.12, at port 1723, but he couldn't see me. You mentioned the server needs to be configured with a range of ip's to hand out. Where do I do that on an xp machine? I also added netBeui per some discussion I read, but that did not good. I added the pptp server to port 1723 because I read it but i'm not sure if I need to do that or not. I thought programming was frustrating!!! Thanks for the help guys. If you need more info about the setup let me know and I will give every setting I have.

Ok, with that IP you are definately not getting a network IP. That range is a microsoft range the machine gives itself if it cannot find a dhcp server. Now to clarify, your VPN server is XP? I am not real adept with XP, but it is similar to 2000 I've heard. Does it use RRAS to set up the VPN connection? Sorry, just want to make sure were on the same page! Matt Wray

The machine I am attempting to connect to is a windows xp machine with 2 nic's. One goes to the dsl router, and the other to the local network hub. I have selected pptp as the connection type on my end, but I noticed the type of connection the router makes to the internet is ppoe. To receive incoming connections you create a new connection and tell it to accept VPN connections. There are options like assign Ip, or allow remote to specify its own, and allow connection to my local network (which I have checked). The strange this is that I can connect to the remote machine and once connected I can ping the host. I'm not even sure which side the problem is on. Mine or the host machine.

The problem sounds like it is on your VPN server side. Your machine can connect and ping the server, good. You are not getting IPs for the network. The assign an IP, this is on your server? And you say you have this checked? If not you should, that is probably where your running into trouble.. Matt Wray

Jacklin,
Have a look at these 2 links. It appears that XP cannot be a VPN server, but the remote desktop may be what your looking for.

Per Matt's suggestion I went into the incoming connections properties, and assigned a range of IP's for the machine to hand out. This did allow me to see the machines on the remote network, but they are not able to see me. I am able to file share with the host, but not other clients in the remote network. I'm getting warmer, but I must have some settings crossed somewhere. Thanks again Mattwray for all of your help thus far.

Hi I’m
One of those dangerous self taught individuals so check every thing I say, the problem is don’t know what I don’t know until I try to do something I haven’t done before.
I had a problem getting my home network to work after upgrading 98 server to XP and using Winroute Pro to route and fire wall for 4 clients (95 –98). Initially I could not get anything to work, but discovered in the add protocols drop down “Advertising Protocol” this dropped the VPN that XP Pro appears to set up by default and everything works just like it did before I upgraded to XP.
Try turning on Advertising Protocol.

Good luck

I have been reading all of your ideas here. Can I assume that if I want a VPN I need XP Pro (for remote server access) and XP (home or pro) on the exterior machine.
Simple as that?

Thanks

No, you don't need to have XP to VPN. Win2k server or XP can serve as host, and 98, NT, 2k, and XP can be clients... Matt Wray
