On my desktop, with the latest VPN client installed, it seems to have two IP addresses associated with it. And yet, I'm not sure this is supposed to be the case. Is this normal? What is the function of the "second" address?

One of the two addresses is assigned by the VPN server once you connect. The other one seems to be controlled by what's in the Windows control panel settings. By default, it's trying to use dhcp - which never succeeds - [even though the main LAN address is set correctly by dhcp].

Win XP Pro SP2.

Thanks

Yeah, I get the same thing. I believe it is normal. All works fine for me. I think it is this way because your VPN client is like a personal router. A router needs two IPs (outside/inside). The 169.x.x.x (or similar, I forgot exactly) address that gets assigned can be ignored, from my experience.

Well that makes sense, but someone else on this forum asked my why mine was showing two addresses, and his only shows one.

Yes, that would be me Smile

My Kerio VPN adapter (when connected):
Ethernet adapter Kerio VPN:

        Connection-specific DNS Suffix  . :

        Physical Address. . . . . . . . . : 44-45-53-54-40-08

        NetBIOS over Tcpip. . . . . . . . : Disabled

I did nothing special. Just installed the VPN adapter and gave it a fixed IP (the one I also reserved for me in my KWF user settings).

A VPN adapter is just a virtual NIC, so I don't think it is supposed to or needs to work like a router...

I think that's it. I gave my VPN server a static IP but allow it to hand out dynamic IPs in a different subnet, so the clients are set to dynamic configuration. That results in the Kerio client receiving two IPs, one as assigned by the Kerio VPN server and the other seems to be generated by Windows (the default "no defined network" IP, 169.x.x.x I think, or similar.

I wish Kerio would comment on this...

winkelman if you take out your ip assignment in Windows (and set back to dynamic) do you end up with two IP addresses on the vpn adapter?

Just FYI...

Here's my VPN client ipconfig while connected to Kerio VPN server from my client machine. Shows the two IP addresses. I see now that, probably, getting two IPs is the result of having "Autoconfiguration" enabled (169.x.x.x). I suppose that could be turned off.

Hi Frank,

Yes your setup is the same as mine.

I tried setting the VPN client IP addr to a static one, and also configured the server to use this static address for my vpn login.

However, once I did this I could no longer connect to the vpn server. What's worse, I can't set it back the way it was on the server, because I can no longer get into the admin console!

The office is a 3hr drive away...nobody else there at the moment. Damn! Perhaps if I wait for an hour the connections will time out...
