Topic: Why does SME 5.6 server’s pptp server give out a loopback su

[SSBN]

Why does SME 5.6 server’s pptp server give out a loopback subnet mask of 255.255.255.255.  When I was playing around with SME 6.0 this seemed to limit the pptp server to only allow one user at a remote location behind a router using nat to map a network drive. If one person mapped the drive the other couldn’t even ping the server with the shares on it. Will this happen with 5.6 or was that just a 6.0 bug. If it is related to the subnet mask and is there a way to change it to a 255.255.255.0 one.

Thanks

What makes you say that it does? The PPTP server sets up a point to point link. A point to point link only has a source address and destination address. It doesn't have a subnet mask.

The PPTP server only supports a single connection from any particular source IP address.

Charlie thanks for responding I am great full for your answers. When I connect my windows xp computer to my vpn and do an ipconfig I get an ip and a subnet mask. I have researched a bit and found it is windows that give the subnet mast of 255.255.255.255.

So I can only connect one computer with the same ip at a time. That really sucks. Do you no of any SME software that will allow multiple connections from the same ip address or a way to modify the SME vpn setup. I currently use windows 2000 for my pptp vpn and it will let me connect multiple computers from the same ip address. But it disconnects them three to five times a day. I don’t really like windows servers and am trying to find Linux solutions.

Any suggestion would be great.

Here is my setup if you would like to suggest things

Main office.
Firewall with SME5.6 behind it. Client computer are connected to the SME server for DHCP and it is a gateway as well

Remote office

Linksis router with 4 computers behind it. All the computers are XP.

What I want to do is have the computers at my remote office map a drive to the SME server at head office via VPN.

I wanted to do this with SME5.6 is it at all possible.

SSBN,

Why not setup an SME at the remote location and setup IPSEC between it and the SME at the main office, that would be my suggestion.

That way you only need one VPN connection to connect all clients at remote with all clients at main office, right?

That would be the best way to go. I do wish I could. But the only high speed internet here under 1000 a month only has dynamic ip addresses. I use no-ip.com at my main office to give the office a static domain name. But from what I understand you can’t link ipsec VPN’s using a service like that. Have to have the static ip’s. I hate to go back to the windows VPN server but it is looking like I may have to. When I tested SME 6.0 it would let me log onto the vpn server from more than one computer. But only one could map network drives. Was I just confusing the VPN server or will SME6.0 support this type of conection.

Well, technically, it will work until an IP at either end is reassigned. That goes for PPTP connections too, so I really don't see the difference here. Whenever an IP at either end changes, you'll have to tear-down the VPN and bring it back up again. That's life with dynamic IPs, and it goes for any network connection that I know of, so PPTP won't help you here either.
