Bret,

You can provide a more detailed answer then the one give.  One of the 
questions that should be posed is what type of VPN type is Brian using?

VPN Software (i.e. Shim software, V-ONE, etc)
VPN Hardware(i.e. New Oak Technologies, Network Alchemy, etc)
Client software (Microsoft PPTP, Dial/IP, FW-1 SecuRemote))
What type of firewall ?
        Hardware?
        Software?
        What VPN product is it compatible with?
        IPSEC compliant
        Easy to use?

Services that will be utilizing VPN tunnel (FTP, HTTP, HTTPS, Proprietary)

/cheers

Hmm well firstly try and terminate the VPN either immediatly prior to the
firewall, or preferably on its own segment of the firewall. You don't want
it to go straight through since it is a tunnel (think someone else said
that too).

If you are doing what I think you are doing (running the VPN on the same
linux box as the firewall) then it will be terminating at the firewall and
you should be able to filter it normally.

Probably didn't help since the ports you open depend on the type of VPN 
you
are using.. try not to use the MS one though.. not so good..

Cheers,

Bret
