After I connected my D-Link DIR 655 router to my Siemens SpeedStream DSL modem over PPPoE and following this advice to flush my system config, my MacBook Pro running Mac OS X Snow Leopard 10.6.8 can establish a VPN connection to my company's VPN server. However, there seems to be no traffic that can go through the VPN connection; it can't access any hosts on the remote site. Some diagnostics:
- The Windows laptop within the same Wi-Fi LAN can connect VPN and can talk to hosts on the remote site. This may rule out errors with the router / modem / remote hosts.
- The same Mac OS X laptop can connect VPN and can talk to remote hosts in our satellite office,
- Nothing remarkable in
/var/log/system.logis seen - Tried rebooting the Mac OS X laptop a few times. Tried set up a new VPN connection.
- If I send all traffic over the VPN connection, then it can connect to any Internet host.
- The Network setup panel for the VPN connection shows send activities but no receive activities.
ifconfig shows:
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1444 inet 10.XXX.XXX.XX --> 10.XXX.XXX.1 netmask 0xff000000
What else could I try?
