    Hi -

    I am trying to establish a PPTP connection through my OpenBSD 3.0
    firewall/router. I use the i386 install of 3.0. It appears that my firewall is
    not allowing gre to pass through though. I am allowing all outbound
    connections, but (obviously) limiting inbound connections. I have a rule to
    allow my VPN server and my workstation (WinXPPro) to pass gre:

    pass in log quick on $Ext proto gre from $VPN to any
    pass out log quick on $Int proto gre from any to $VPN

    Where VPN is a list of the IP addresses of my employer's VPN servers. Also, I
    use PPPoE, as I have ADSL. Can alyone provide me some tips on getting this to
    work? I never had a problem in 2.9, but since moving to 3.0 have not been able
    to get this to work. I am using the GENERIC kernel with 'option GATEWAY' being
    the only thing I have uncommented. I am not seeing anything unusual in my logs.

    Thanks in advance,

    Greg
