firewall filter set help

[stilesjw]

I've setup a VPN at work and have successfully connected remotely via both WinXP and Mac OS X. And using a lmhost file, I can successfully map drives etc (WinXp only, I still have to connect via IP on OS X). This is set up on an appliance which is a combo router, firewall, and VPN server.

My firewall's default action is that if no filtersets are activated, all incoming traffic is blocked except for the VPN ports which I've openned. However as soon as I add a filterset to my firewall to tell the router not respond to external ping requests, I no longer can VNC, Remote Desktop, map network drives (via IP or NetBios) or anything through my VPN connection.

Any body have any clues or know of a good firewall filter set reference?

Thanks,

This is beyond the typical basic SOHO networking discussions that takes place around here, so you may not get too many meaningfully responses on this. Besides, filtering logic and functionality varies greatly between products.

I'm not sure, but I would assume your machine VNC, VPN, etc would need to be accessible via a inital ping. It would really depend on the system that you were using for your firewall. If it was iptables(linux) or some oddly expensive Windows based, or possibly a Cisco PIX box?

I'm just browsing along, answering all these problems with solutions, but... you haven't given enough environment details to help me help you in any way.

Also.. if it works without the firewall running, and you pop up the firewall, perhaps you have a FW config issue?
