It sounds like the GRE protocol (47) is not enabled or that the firewall on the router is blocking port 1723 and/or port 500.

Last I heard Comcast did not impede GRE protocol or either of those ports.

If you are using a Linksys WRT then you are not alone. When this problem has come up it usually happened after a router firmware upgrade. The normal "fix" was to disable the internal firewall and then fiddle with it until it did what it is supposed to.

Hope that may be of some help.

You got a router or personal FW in play?

I have a router, but the firewall was disabled by comcast supposidly.

If you have a router, did you purchase it?

If you have a DSL or CABLE modem, then you might have NAT or a public IP address, as those are not firewalls, but sometimes called firewalls.

If you have a public IP you might want to purchase your OWN NAT Router in order to protect your network.

Is the router you speak of a stand alone item (separate from your cable modem)? If so, what is the brand and who configured it?

If it came as part of a Comcastic promo package, do you have access to the web interface and if so have you checked to make sure that the GRE protocol was not disabled by default?
