vpn into sbs

corosus · 12-22-2007, 05:10 AM

hi

I'm using kvpnc to connect to the VPN at work. The server there is a sbs 2003 so i'm using pptp.
I get a connection and i get an IP but i can't seem to ping anny resource off the network other than my machine
When i boot up my old win2000 machine all works fine, so i know it's not router-related.

does annyone know what might be the cause of this?

thank you

What results do you get from traceroute or netstat -r?

Hi Harry,

thanks for the help

netstat -r

default * 0.0.0.0 U 0 0 0 ppp0

traceroute 172.16.1.135 (the sbs's servers internal adress) does not give annything

thank you again for your help

I cannot see anything wrong with your routing. It show me that the ppp connection is established and is configured to be the default route. Are all the resources on the same LAN as the SBS server, or are they behind a gateway?

in the same lan, but nothing on the lan is pingable, not the server, not the gateway...

I'm not sure what the answer to this question will give you; but, when connected can the server ping the IP address of the ppp connection? This maybe a SBS quirk: I know from experience that SBS integration with none MS O/Ss can be hard to achieve.

The result of ifconfig
