    pptp vpn issues with mac

    I had recenetly setup a pptp vpn server on centos 5.8 ..
    every thing is working fine. i can coonect perfect ok from a windows machine and works great

    but one vpn user has a mac notebook

    MacBook Pro os is X lion 10.7.5

    it connects fine but I cannot do a RDP to a windows 7 machine

    But if this win7 machine is given a public ip I can remote desktop from the same mac notebook to the ip and it works fine

    my error logs show

    Re: pptp vpn issues with mac

    Dear All,

    I did a little investigations since i just had the look at the mac notebook today ( actually its a personal notebook of my manager) .

    then i found that i was not able to ping my default gateway.
    then i realized that windows VPN connection has a option... use default gateway on the remote network.
    how can i achieve the same in the mac notebook --- MacBook Pro os is X lion 10.7.5


    apprecite your help

    regards

    simon
