The only reason that worked for you is because you are making a L2TP or IPsec VPN connection and not a PPTP connection your router IP was in the same range (10.0.0.x) as your remote network and you had to change it to avoid an IP conflict. The issue, again, is that the device does not translate (NAT) protocol 47 back to the client correctly (often called "PPTP passthrough" on other devices). With L2TP and IPsec VPNs, that is not needed which is why changing the IP seems to work for some people but not others. The only way to fix the PPTP issue is to ditch the device for something else or get it bridged and add your own router. I chose to purchase an Arris TM822G and an ASUS wireless router. I get better speed and can configure it myself. And I don't have to pay $8/month any more to lease a device that isn't configured correctly for what I need anyway, so this will effectively save me a lot of money in the long run. Also, again for the record, it's honestly not reasonable to expect Comcast tier 1 support to be able to help you. I can assure you that anyone who is proficient in IP-based networking enough to understand this issue will not be working on a customer-facing tier 1 support platform. This problem COULD be fixed pretty easily with a configuration change or firmware update, but given the number of these devices out there, I'm pretty sure that if they wanted it fixed it would have been fixed a long time ago. Either that or someone decided it wasn't worth risking bricking thousands of modems over a firmware patch (which I must admit that I understand as well.) Please don't take this the wrong way. I know you're trying to help and your actions did, in fact, fix YOUR issue. But you are definitely not using a PPTP VPN tunnel. I'm just trying to explain why this won't work for others who are attempting to establish a PPTP connection so they don't go nuts when it doesn't work!
