I have an Amazon Linux machine running in an Amazon EC2 instance.
I am connecting to my office's VPN as follows:
sudo pppd pty "pptp pptp.<DOMAIN>.com --nolaunchpppd --loglevel 2 --debug" file /etc/ppp/options.pptp user <MYUSER> password <MYPASS>
I can see in /var/log/messages that I am connecting:
CHAP authentication succeeded
But when I ping a server located within the remote network it just hangs:
ping -I ppp0 newdev.<DOMAIN>.com
I can ping the machine without -I, but I get its external IP address:
ping newdev.<DOMAIN>.com
PING devserver.<DOMAIN>.com (xxx.xxx.xxx.xxx) 56(84) bytes of data.
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=1 ttl=109 time=15.5 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=2 ttl=109 time=15.4 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=3 ttl=109 time=14.5 ms
I'm sure I'm missing something, I'm just not sure what.
Routing table when connected:

If newdev.<DOMAIN>.com resolves to the external address, then I'd expect this behavior. Can you ping its internal address with -I? – Paul – 2011-11-22T02:03:40.233
No, the same thing happens. It just hangs.
If I connect to the same VPN from Windows 7 (and default gateway disabled) it resolves to the internal ip. – user1058765 – 2011-11-22T02:07:04.533
I meant IP address - are you saying ping hangs when you ping the internal IP address? – Paul – 2011-11-22T02:13:18.407
Yes, so the internal ip is 192.168.7.7. If I ping that it just hangs. – user1058765 – 2011-11-22T02:14:28.777
