Hi Everyone,

I have an OpenBSD 3.3 transparently bridged packet filtering firewall.  I
would like to enable a VPN connection through the firewall into a Win2K3
server that sits behind the firewall.  

I am finding conflicting information on what ports/protocol to open up.
Microsoft is saying protocol ID 47 and TCP port 1723 both inbound and
outbound.  If that's true, then something like the following should work:


pass in quick on ext_if proto 47 from any to any
pass out quick on ext_if proto 47 from any to any


pass in quick on ext_if proto tcp from any to any port 1723 keep state
pass out  quick on ext_if proto tcp from any to any port 1723 keep state

I had not luck with the above.  If I disable PF I can connect fine, so I
know for sure that the problem has to do with PF blocking my access.

To complicate matters, I've found other references to protocols 50 & 51 and
port 500.

I'm hoping that one of you who has this working can let me know what I need
to config in order to allow my VPN connection to pass through the firewall.

Thanks,

Dave
